(ichimunki) re x 5: Summing the elements of multiple arrays into a new array

It's a good warning in the sense that sometimes you will have variables that you intended to set get into your assignments still undefined and this lets you know, in a non-fatal way, that something may be wrong.

On the other hand, you can do like the Slashdot crew and customize a SIGWARN callback to muffle this output.

No need to go through all that on current versions of perl.... If I know I'm in a 5.6.0 or newer perl environment, the first few lines of my code are usually: `#!/usr/bin/perl -T use warnings; no warnings "uninitialized";` [download] I find that this bounds me enough to catch my screw-ups, but not enough to inhibit my coding style.. -Blake	[reply] [d/l]
