There's no practical issue in normal code, but it behaves in a way that feels unintuitive. I have never used NaN or Inf in code, and never would. I would be using Math::BigFloat for anything that odd.

I guess the part that I don't like is that NaN and Inf are valid return values, more than anything. Neither are integers - though I also realize we can't change how int works, it feels very unintuitive.

The +0 was a quick hack I would use to coerce a string into a number - in lieu of $num =~ /^\d+$/ or $num=0 for untainting - I didn't know Inf and Nan were valid integers in Perl until last week (one of those things I thought I knew but had just never encountered - this is up there with when I first head about using _ in code :D

I can live with NaN+0=NaN<code> and <code>Inf+0=Inf, but I really do think int('information') should be zero rather than Inf!
