Re^2: How to creater your own Perl modules/libraries?

This was an excellent post, but there's one caveat:

# Don't forget this:
1;

Note that this is not necessary. :-)

UPDATE: If you don't already know that this is a joke, then please ignore it, or your module-writing life will be harder than it needs to be. If you don't want to ignore it, then at least read perlmod and the linked page carefully to see why it's a joke.

Hi, Just want to confirm that the 1; is not necessary?	[reply]

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.
