in thread Warning counter

Warn takes a list! Heck, die takes a list, too! Has this always been so? All this time I've been using . to concat.

Where did I get the idea that it had to be one string?

Not that it matters a whole lot, but it's just slightly nicer to use commas.

    Indeed it has. If you look at the top of the warn and die docs you'll see the prototype func LIST meaning it takes a list. Although this isn't terrifically relevant to the output as the list is concatenated into a single string and the same behaviour goes for the arguments to the __WARN__ and __DIE__ signal handlers. So it's really just for your convenience, such is perl's way :)
