You have a point here, and a very interesting one. I've entered an entry
for that in Dev Projects so that we don't forget it.

True and sad :-)

Yes but longer. Two different worlds. When a re-implementation becomes
available at the C/C++ level, I'd be happy to re-write the Text::Query module
to take advantage of it. This will trigger discussions because some people
love to have Perl only programs.

When you say at some point, you mean not for your first release, right ?
I agree that a prepare would be nice, with a syntax tree, possibly optimized
as a result. Resolving the query would then only require using an already
parsed query instead of re-parsing it every time. Let me know when you want
to start a discussion on that.
Had any success in geting a login on CPAN ?
