You did mean "use diagnostics" or "-w" right?  Use strict doesn't care
about such things.

The warning you are talking about is:

    Argument "blahblah" isn't numeric in numeric eq (==) 
    at blah.pl line 20 (#1)

And in diagnostic form:
    
    (W numeric) The indicated string was fed as an argument 
    to an operator that expected a numeric value instead.  
    If you're fortunate the message will identify which 
    operator was so unfortunate.

Some of the diagnostic message are worth reading if only for a laugh :)
