in reply to What is %_

With the Perl special variables, the entire typeglob is declared (global in package main), even though only one or two types actually may be used by Perl. So you get lots of extraneous globals available, like @*, %_, @@, %%, $INC, etc.

Unless you're writing obfuscated code, it's probably a better idea to create your own lexical variable.
