I use it at work, but not as recusive descent; I write a grammar using
it.

I had to fix a couple bugs, and it can be confusing getting the
grammar to be unambiguous, but I like the resulting high-level code.

As with other grammar-oriented parsers, the error messages leave a lot
to be desired. If I ever find time, I'd like to try switching to using
it in a recursive descent way; that usually gives better error messages.
