I'd like to debug this, but not sure how to proceed. Actually, it's not infinite recursion, just deep recursion, where deep is defined as > 100, or is it >= 100, I can't remember offhand. As you've noted, everything should still work - it's just a warning, and as such it can be turned off with C<no warnings "recursion">. I was (and still am) of the opinion that 100 is a little low nowadays, and sent a patch to p5p a couple of weeks ago to raise the limit to 1000, which is what parrot uses, I think. Unfortunately, everyone else seemed satisfied with 100, or at least no-one else spoke up in favour of the patch, and so the limit will remain at 100. I didn't want to have to put C<no warnings "recursion"> in Devel::Cover, as it seems to high a level to me. Maybe it should go in B::Deparse. But then I've also hit a similar problem using Parse::RecDescent to parse a language, which I why I wondered about upping the limit. But I suppose I'll turn off the warning from Devel::Cover. That seems the most pragmatic solution at the moment. In the meantime, please just ignore the noise. Or maybe add -X to your command line, if you're feeling brave. -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net
