Yeah ... if you *don't* know the difference between a DFA and an NFA,
you're likely to find yourself in over your head. Having said that,
this is eminently learnable stuff and pretty self-contained, so somebody
who had the time and interest could make themselves into an expert in
a reasonable amount of time. I'm not really eager to become the
project's regex guru, but only because I have ninety-nine other things
to do not because I don't find it interesting. Right at the moment I'm
probably far enough up the learning curve that I can fix the backref
problem faster than anyone else, so I'm kind of inclined to go do that.
But I'd be entirely happy to let someone else become the lead hacker in
this area going forward. What we can't do is just pretend that it
doesn't need attention.
In the long run I do wish that Spencer's code would become a standalone
package and have more users than just us and Tcl, but that is definitely
work I don't have time for now. I think somebody would need to commit
significant amounts of time over multiple years to give it any real hope
of success.
One immediate consequence of deciding that we are lead maintainers and
not just consumers is that we should put in some regression tests,
instead of taking the attitude that the Tcl guys are in charge of that.
I have a head cold today and am not firing on enough cylinders to do
anything actually complicated, so I was thinking of spending the
afternoon transliterating the Tcl regex test cases into SQL as a
starting point.
