2 finish byte <-> utf8 and localencoding <-> utf8 conversions
3 make substr($bytestr,0,0,$charstr) do the right conversion
4 add Unicode::Map equivivalent to core
5 add support for I/O disciplines
6 - a way to specify disciplines when opening things:
7 open(F, "<:crlf :utf16", $file)
8 - a way to specify disciplines for an already opened handle:
9 binmode(STDIN, ":slurp :raw")
10 - a way to set default disciplines for all handle constructors:
11 use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
12 eliminate need for "use utf8;"
13 autoload byte.pm when byte:: is seen by the parser
14 check uv_to_utf8() calls for buffer overflow
15 make \uXXXX (and \u{XXXX}?) where XXXX are hex digits
16 to work similarly to Unicode tech reports and Java
17 notation \uXXXX (and already existing \x{XXXX))?
18 more than four hexdigits? make also \U+XXXX work?

33 support "use Thread;" under useithreads
35 - create new interpreter in a different thread
36 - exchange data between interpreters/threads
37 - share namespaces between interpreters/threads
38 work out consistent semantics for exit/die in threads
39 support for externally created threads?
43 auto-produce executable
44 typed lexicals should affect B::CC::load_pad
45 workarounds to help Win32
46 END blocks need saving in compiled output
48 fix comppadlist (names in comppad_name can have fake SvCUR
49 from where newASSIGNOP steals the field)
52 CPP-space: restrict what we export from headers when !PERL_CORE
53 header-space: move into CORE/perl/?
54 API-space: complete the list of things that constitute public api
57 make configuring+building away from source directory work (VPATH et al)
58 this is related to: cross-compilation configuring (see Todo)
59 _r support (see Todo for mode detailed description)
60 POSIX 1003.1 1996 Edition support--realtime stuff:
61 POSIX semaphores, message queues, shared memory, realtime clocks,
62 timers, signals (the metaconfig units mostly already exist for these)
63 PREFERABLY AS AN EXTENSION
64 UNIX98 support: reader-writer locks, realtime/asynchronous IO
65 PREFERABLY AS AN EXTENSION
66 IPv6 support: see RFC2292, RFC2553
67 PREFERABLY AS AN EXTENSION
68 there already is Socket6 in CPAN
71 figure out where the PV->NV->PV conversion gets it wrong at least
72 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
73 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
74 (?:9|8999\d+) and the like.
77 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
78 be in some systems the only thing working as quadtype and uquadtype.
79 more pain: long_long, u_long_long.
82 deprecate traditional/legacy locales?
83 How do locales work across packages?
84 figure out how to support Unicode locales
85 suggestion: integrate the IBM Classes for Unicode (ICU)
86 http://oss.software.ibm.com/developerworks/opensource/icu/project/
87 ICU is "portable, open-source Unicode library with:
88 charset-independent locales (with multiple locales
89 simultaneously supported in same thread; character
90 conversions; formatting/parsing for numbers, currencies,
91 date/time and messages; message catalogs (resources);
92 transliteration, collation, normalization, and text
93 boundaries (grapheme, word, line-break))".
94 Check out also the Locale Converter:
95 http://alphaworks.ibm.com/tech/localeconverter
96 There is also the iconv interface, either from XPG4 or GNU (glibc).
97 iconv is about character set conversions.
98 Either ICU or iconv would be valuable to get integrated
99 into Perl, Configure already probes for libiconv and <iconv.h>.
102 make RE engine thread-safe
103 a way to do full character set arithmetics: now one can do
104 addition, negate a whole class, and negate certain subclasses
105 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
106 intersect characters/classes, like described in the Unicode technical
107 report on Regular Expression Guidelines,
108 http://www.unicode.org/unicode/reports/tr18/
109 (amusingly, the TR notes that difference and intersection
110 can be done using "Perl-style look-ahead")
111 difference syntax? maybe [[:alpha:][^abc]] meaning
112 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
113 (maybe bad, as we explicitly disallow such 'ranges')
114 intersection syntax? maybe [[..]&[...]]?
115 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
116 =bar= could be done with Unicode, though, see the Unicode TR #15 about
118 http://www.unicode.org/unicode/reports/tr15/
119 this is also a part of the Unicode 3.0:
120 http://www.unicode.org/unicode/uni2book/u2.html
121 executive summary: there are several different levels of 'equivalence'
122 trie optimization: factor out common suffixes (and prefixes?)
123 from |-alternating groups (both for exact strings and character
124 classes, use lookaheads?)
128 use fchown, fchmod (and futimes?) internally when possible
129 use fchdir(how portable?)
130 create secure reliable portable temporary file modules
131 audit the standard utilities for security problems and fix them
135 alternate runops() for signal despatch
136 figure out how to die() in delayed sighandler
137 make Thread::Signal work under useithreads
140 sort out the spawnvp() mess for system('a','b','c') compatibility
141 work out DLL versioning
144 introduce @( and @) because group names can have spaces
145 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
146 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
147 Configure doesn't yet probe for usleep/nanosleep/ualarm but
149 floating point handling: nans, infinities, fp exception masks, etc.
150 At least the following interfaces exist: fp_classify(), fp_class(),
151 class(), isinf(), isfinite(), finite(), isnormal(), unordered(),
152 <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these),
153 fp_setmask(), fp_getmask(), fp_setround(), fp_getround()
154 (no metaconfig units yet for these).
155 Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do,
156 unfortunately, exist), and unorderedl().
157 PREFERABLY AS AN EXTENSION.
158 As of 5.6.1 there is cpp macro Perl_isnan().
159 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
160 both arguments are IVs/UVs: it sucks that one cannot see
161 the 'carry flag' (or equivalent) of the CPU from C,
162 C is too high-level...
163 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
164 automate testing with large parts of CPAN
165 turn Cwd into an XS module? (Configure already probes for getcwd())
166 mmap for speeding up input? (Configure already probes for the mmap family)
167 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
168 setitimer, getitimer? (the metaconfig units exist)
171 keep filenames 8.3 friendly, where feasible
