-Modules needed
- X/Motif/Tk etc.
- Curses

Tie Modules
VecArray Implement array using vec()
SubstrArray Implement array using substr()
ShiftSplice Defines shift et al in terms of splice method
Would be nice to have
- Profiler
pack "(stuff)*"
Contiguous bitfields in pack/unpack
lexperl
Bundled perl preprocessor
Use posix calls internally where possible
- const variables
gettimeofday
- bytecompiler
format BOTTOM
- $obj->can("method") to probe method inheritance
-iprefix.
-i rename file only when successfully changed
All ARGV input should act like <>
- Multiple levels of warning
- .= shouldn't complain about undefined under -w
report HANDLE [formats].
- tie(FILEHANDLE, ...)
- __DATA__
support in perlmain to rerun debugger
- make 'r' print return value like gdb 'fini'
+ regression tests using __DIE__ hook
+ reference to compiled regexp
+ lexically scoped functions: my sub foo { ... }
+ lvalue functions
+ regression/sanity tests for suidperl
+ Full 64 bit support (i.e. "long long")
Possible pragmas
debugger
Optimizations
constant function cache
switch structures
- foreach(@array)
+ eval qw() at compile time
foreach (1..1000000)
foreach(reverse...)
Set KEEP on constant split
Shrink opcode tables via multiple implementations selected in peep
Cache hash value? (Not a win, according to Guido)
Optimize away @_ where possible
- sfio?
"one pass" global destruction
Optimize sort by { $a <=> $b }
Rewrite regexp parser for better integrated optimization
+ LRU cache of regexp: foreach $pat (@pats) { foo() if /$pat/ }
Vague possibilities
ref function in list context
- Populate %SIG at startup if appropriate
- sub mysplice(@, $, $, ...)
data prettyprint function? (or is it, as I suspect, a lib routine?)
- Nested destructors
make tr/// return histogram in list context?
- undef wantarray in void context
Loop control on do{} et al
Explicit switch statements
- perl to C translator
- multi-thread scheduling
built-in globbing
compile to real threaded code
structured types
- paren counting in tokener to queue remote expectations
autocroak?
Modifiable $1 et al
- substr EXPR,OFFSET,LENGTH,STRING
- locally capture warnings into an array
