Extended Regular Expressions library. alpha but usable.

Current feature: Named subexpressions. (?.var=pattern) to capture,
\{var} to reference. Comes in useful when combining several regexps into a
bigger one, since you don't have to worry about a new subgroup changing
all the matchdata indices.

Usage example:

 include XRegex
 
#create a new xregexp:
 a = rx("(?.num=\\d+):(?.alpha=[\\w']+)")

#match it against a string
 b = a.match("120:abc")

#and the variables can be accessed in the old numeric style (if you
#insist)
 puts b[1]

#or by name
 puts b['num']
 puts b.alpha
