Hi,

This is to remind everyone of the formal review of Eric Niebler's  
xpressive library. The review period is scheduled to end Sunday,  
September 18.

I want to especially point out the xpressive is not just another  
'regex' library. It goes beyond the scope of regular regex (no pun  
intended) engines.

Here is what Eric has to say:

"Although xpressive's primitives are regex-ish in nature, xpressive  
is far more than just a regular expression engine. It is a pattern  
matching engine with the power of context-free grammars. By allowing  
you to embed one pattern in another by reference, xpressive lets you  
find patterns in data that are recursive in nature. Problems that are  
intractible with "classic" regular expressions, such as matching  
balanced nested parentheses or matching XML tags, are simple with  
xpressive. So xpressive is more rightly thought of as a context-free  
grammar engine with exhaustive backtracking. The goal is to provide  
one framework and one set of pattern matching primitives that scales  
from simple strstr-style grepping, through ordinary regexing, all the  
way to full-blown parsing."

For a glimpse of what xpressive can do look at "Grammars and Nested  
Matches" here:
