Re: Is your module clobbering predefined variables?

Programming Perl, 3rd Edition includes a nice little module that you might want to look at. It's called Underscore and you call it like: no Underscore; It simply warns you if you try to use $_ without localizing it.

Cool! That's one for the debugging toolkit.. throw it at misbehaving scripts for a quick check, much like warnings and strict. Makeshifts last the longest.	[reply]

I started searching and wandered upon a cool link. Tom Christiansen posted the source for Underscore.pm as well as a test script (both of which appear in the Camel). Update! bikeNomad posted a similar one here and says it's from the Perl Cookbook.	[reply]
