lexperl
Bundled perl preprocessor
Use posix calls internally where possible
- gettimeofday
+ gettimeofday (possibly best left for a module?)
format BOTTOM
- -iprefix.
-i rename file only when successfully changed
All ARGV input should act like <>
report HANDLE [formats].
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")
+ Generalise Errno way of extracting cpp symbols and use that in
+ Errno and Fcntl (ExtUtils::CppSymbol?)
Possible pragmas

Optimizations
constant function cache
switch structures
- eval qw() at compile time
- foreach (1..1000000)
foreach(reverse...)
Set KEEP on constant split
Cache eval tree (unless lexical outer scope used (mark in &compiling?))
Cache hash value? (Not a win, according to Guido)
Optimize away @_ where possible
"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
- data prettyprint function? (or is it, as I suspect, a lib routine?)
make tr/// return histogram in list context?
Loop control on do{} et al
Explicit switch statements
structured types
autocroak?
Modifiable $1 et al
- substr EXPR,OFFSET,LENGTH,STRING
