in thread Perl 5 Optimizing Compiler

From Type system (wikipedia):

Certain languages, for example Clojure, Common Lisp, or Cython, are dynamically typed by default, but allow this behaviour to be overridden through the use of explicit type hints that result in static typing. One reason to use such hints would be to achieve the performance benefits of static typing in performance-sensitive parts of code.

So, to get close to (statically typed) Java in terms of speed, Perl 5 would need to make significant tweaks to its type system and the way it handles polymorphism, as indicated by chromatic's response. See also MJD perl.com article (2001), which explains why making Perl as fast as C is problematic.

[LanX]: memories....I missed my connection while chatting
[Discipulus]: in this case Corion we are speaking about software licensing: evry year or two we must rescan the whole ced to produce an excel report, while at every activation / disactivation we update a black box DB: i said that i a week i can produce the perl to..
[Discipulus]: rend out the xls IF i have access to the DB
[choroba]: LanX I miss working in a bank sometimes...
[Corion]: Discipulus: Ooof. Especially yearly things are things I like to automate instead of trying to remember how I did things last year...
[Corion]: And the second rule that I've learned is, that there is no one-off job, so writing a program for it pays off almost immediately. The third rule is to give all my programs numbers and have them reproduce that number in the name of their output files. :)
[Discipulus]: the true part is that also specification change between years.. but well our job is cheap but dont abuse of us.. ;=)
[LanX]: Choroba: do you miss chaos with ties? apply at the US government.. ;)
