Certainly modules have considerable *semantics* and effect execution.
But they have little *meaning*. There's all sorts of semantics
associated with classes, but that's incidental to the meaning of a class
-- a class is a set up behaviors common to a kind of object. A module
is just a pile of stuff the programmer likes to keep together. It's
essentially a clerical feature.
