Good point. You lose the uc bit, but its awfully tight.

I think I was reacting more to the parameter unpacking. The sub is handed a compound, and the parameter is stored and then broken apart. I tend to think of that breaking as part of the unpacking process, so in essence get two params passed to the sub in a particular format, hence my "first" line produces those two variables.

It all comes down to chasing errors, I suppose. I've gotten the habit of putting in a print (or warn) at subroutine entry with the parameters passed controlled by a debug variable. With the one-liner, you can't really do that. But then again, its so bloody simple, perhaps its not necessary.
