Tye's statement was correct. Perl does indeed compare the two values numerically, but the magic of bigint is not triggered. The 0+ doesn't force numeric comparison in this case, it triggers bigint magic.

Well, thanks for playing obvious favorites... but please tell me what I said that was incorrect (other than insisting on bigint when some other module, such as Math::BigInt, might also do the job as well, as ysth pointed out).
Seems to me that "for the numeric comparison to work properly" is unambiguous enough.
Anyway, I'm not sure what you're arguing with, since I never claimed anything tye said (in this thread) was incorrect.
