Hmmm - I can't be a real person, obviously....

I've used Spirit 1 on several projects with great success. I've also
use Antlr on several projects with great success! What's the
difference? Well, Antlr (for me) implies a reasonable amount of
project overhead - building the runtime support, having additional
files to configure, having to deal with the conceptual break between
Antlr and C++. Spirit doesn't. It does mean a compile-time burden,
true, but that burden is the reason I've used Antlr for larger
grammars rather than Spirit.

If that were true of Spirit, it would also be true of a lot of Boost.

I'm sorry, but name calling like that isn't warranted, especially when
you are asserting that your opinion is universally held, when I think
you'll find it's not.
