Lua patterns rule! (Re: Frontier capture)

[Asko Kauppi <asko.kauppi@...>]

I need to give some praise to the Lua authors :) on the courage to go 
upstream with the selected, unique set of regexp's or patterns, as used 
in string.find() and string.gsub().  While I don't have much experience 
with 'real' regexp's, the use of the provided set is compact, easy and 
powerful. Well done!

The only thing that I've missed (which does exist in real regexp's) is 
ability to logic-or strings, not just chars.  I believe this has been 
met by others as well, and is one motivation behind the regex addon 
library.
