\1 and \2 are not stricture errors (use strict does not generate warnings - they are fatal errors). They are warnings, and require warnings to be turned on.	[reply]

I tend to bundle warnings and strict together in a bundle I refer to as "strictures", as in "Always use strictures (use strict; use warnings; - see The strictures, according to Seuss).". True laziness is hard work	[reply]
