Returning Lists From Dynamic Module

[Psionic K]

I think I read something before about using cons in the manual, but now I
can't find it.  I was just wanting to return some alists to Elisp.  I'm
expecting I need to move some values over to Emacs managed memory while
consing them up according to the desired structure, but I don't know the
correct phrase / tools for either of these actions at a low level.
