I probably should have been more careful. It is necessary that your module return something true, and the easiest way to make sure that it does is to put `1;` at the end of the source file ^. All that I was saying was that what is actually returned may be anything* true, including `1`, `"I'm a true string"`, or `[ qw/references are always true/ ]`. To put it briefly: don't leave off the `1;` at the end without a good reason (although the good reason may be “I thought of something funnier”). If you do leave it off, then do a simple test import of your module just to make sure that it can be done. ^* To be precise, this requires that you haven't done something tricky earlier, like `return`ing earlier in the source file.
