There doesn't appear to be a way to force perl to be strict about all your code, but there is an easy way to work through it incrementally. What you could do is test each module, fix any serious errors, and then catch the minor ones later when you have time.

You can "test" the modules by running them, such as:      % perl -w -Mstrict Some_Module.pm This will generate a whole bunch of errors and warnings, or, if things are cool, it will presumably do nothing at all (unless the module actually does something by default). Once you're done, or merely tired of fixing all the bloody errors, you can just run the program normally, whatever that means.
