Posix char classes broken

[Adam Shackleford]

This:

public static void main(String[] args) {
 System.out.println(new Perl5Util().match(/[:digit:]/, 1));
 System.out.println(new Perl5Util().match(/[0-9]/, 1));
}

produces:

false
true

on System.out. It's a bug, no?

thnx,

adam

Eek! I deserve a thousand lashes with my copy of Mastering Regular
Expressions for that one!

I think RegExp (which I'm switching from) allows inline [:posix:], which is
definitely wrong.

thanks,

  System.out.println(new Perl5Util().match(/[:digit:]/, 1));

 I think what you want is [[:digit:]] The POSIX class needs to appear
 inside of a character class.

new Perl5Util().match(/[[:alpha:]]/, a) = false

The expression:

new Perl5Util().match(/[[:alpha:]]/, a)

returns false with ORO 2.0.3, whereas: 

new Perl5Util().match(/[[:alnum:]]/, a)

returns true. I hope this isn't another newbie mistake...
