Trunc. Int context, you know :)

If it's like Perl5, 5.05. But there could be reason to make it an
exception. Dunno on that one. I would say 5.05 for now, until
someone with authority corrects it.
> my int $n = "fdsjfdf" # 0, undef, NaN, or exception?
Likewise here. There could also be reason to have this behave
differently from the last one. Though, I would say 0 for now.

I believe this was the plan. Remember, there was int context and num
context, so a natural extension would be that conclusion.
As for your documentation plan, I think it's a good idea, though I
concur with Dan on Just Do It. Document the language for what best
makes sense now. If there are *big* issues, ask Larry et al. on this
list. For the little ones, use common sense and they will be hashed
out later.
