I haven't the faintest idea, but (a) Benoit alluded to doing this 
eventually and (b) I think there may be hooks in the API for 
it.... My C is still a bit rusty but it's all coming back to me 
;)  It would replace 3 lines of code (DIM, then NEW, then 
checking the offset) with 1, but for most of my uses I need 
access to the submatches so I'd still have to explicitly create 
an object.

I've decided it would also be cool to make available the offsets 
for each submatch (I don't even know how to get at those in 
perl!) so I'll probably add that, and of course all the 
properties need to be read-only, so there'll be at least one 
more version before I'm done with it.  I'd also like to write a 
Replace method that would be sort of like the s/from/to/g in 
perl, except returning a value rather than operating on the 
buffer directly.  (But I'm about to go away for the weekend, so 
I dunno if I'll do anything with it for a couple days.)

Next up after this is a POSIX component just to keep my skills 
fresh ;)  I haven't come up with too many other easily wrapped 
libs that I actually need yet, but I have wanted a few of the 
POSIX functions at times.

I wonder if it would be possible to write something that would 
dlopen an arbitrary shared library and allow access to its 
functions using a mechanism like VB's "Declare" statement.  
Sadly, that's probably beyond my skill level right now and the 
SEGV'ing would be rampant.
