in reply to Why no warnings for 1 in void context?

It is so that the convention of ending a module with 1; won't trigger a warning. Modules must return truth, and it's common practice to put a 1; on the last line to satisfy this criteria.

See perlmod for supporting documentation.

    The final line of a required module isn't in void context - it's the return value of the require. Try putting something else there and you'll see there's no warning. I worked with a guy who put (unfortunately copyrighted) poetry in a string at the end of his modules.

      It is actually always in scalar context. I learned this while trying to be a wise ass with Devel::FIXME.

      Yeah. I like to end modules with 42;
