When I read a phrase like "..module Foo::Bar would be in a file named Foo/Bar.pm" in the original (2006) discussion, and coming from a perspective of not already knowing Perl and trying to learn, it makes me think that maybe 'Foo/Bar.pm' is talking about some kind of internal-to-Perl thing, and not the Unix file system. I prefer to call 'Foo' part of the pathname.

In any case, thanks for explaining. It is difficult, when you can work with Perl only sporadically, to distinguish between actual language syntax and customary usage. Now I feel like I have a better chance of understanding module calls.
