Subtraction and Intersection of Character Sets in Unicode Regular Expressions

Perl 5.8.0 misses subtraction and intersection of characters, which is described in Unicode Regular Expressions (UTS #18). This module provides a mimic syntax of character classes including subtraction and intersection, taking advantage of look-ahead assertions. The syntax provided by this module is considerably incompatible with the standard Perl's regex syntax.
