Re^3: Warning for "unused sub declarations"?

Maybe I'm a little slow, but are you and I talking about two different things? As far as I can tell, your bar routine depends on the global variable $foo which doesn't exist when bar is defined. What I was talking about was the need (or lack thereof) to put a superfluous declaration of all user-defined subs at the beginning of the file.

Actually ... i was wrong. We are talking about 2 different things. I was thinking that by declaring subs "superfluously" you could guard against using global lexicals. I thought that was the reason for declaring subs before hand, other than pseudo-documentation, but turns out i was wrong. speaking of thor ... here's something amusing ... jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l] [select]
