Currently :m doesn't load any modules, it just alters the "context" (what's 
in scope at the prompt), and fails if you ask for a module that isn't 
loaded.  It would make sense for :m +M to behave like :add if M wasn't 
loaded, though.  And perhaps :add *M or :load *M should ignore compiled 
code for M - that's another option.
