Re^2: adding a column of integers

Note that this uses map in void context, which is bad except in newer Perls. It's not so horrible for a one-liner, though.

My, my, my. Another fool who thinks he can appear to be smart by chiming the familiar song about map in void context. And to be really smart he mentions it's not so bad in modern perl. Forget about the map. The damage is done before the map is called. Executing `<>` in list context is slurping in the entire file. You've lost your constant memory solution right there. Regardless of the version of Perl you are using.	[reply] [d/l]

I would use a grep instead of a map... :-)	[reply]
