I agree. In fact the argument for the warning is even stronger for a lexical. A global seen only once... well maybe some other package grabs at it. But a lexical declared but never used is useless. About the only counter argument I can see is that issuing the warning for lexicals will cause a lot of existing code to start yelping. But that's what warnings are for. I for one would like to know about unused lexicals.
