Aha! That makes sense. Thank you (and to the others who replied with similar suggestions). Now, if I do this, can you tell me anything about what's going on under the hood? I.e., is there a performance hit for shoving a 1000's-long list into an anonymous array, and then dereferencing that array to get its length? Or is Perl smart enough to do all of that with one copy of the original list in memory?
