This does exactly the same as "dc = $DC" after my change.  Thus it
appears to work as you expect.

The module recipe already gets a scope.  Thus it's simply a matter of
adding the name in a table of scope names.  I'll look into this.

Suppose we import the "d" module, then using a variable name $d.DC
sounds logical, doesn't it?  Only problem is that using a variable "d"
won't work then, thus perhaps we should use a less obvious name.
#m_d.DC perhaps ("m_" for module).  Or use a more explicit name for the
module, such as "dlang".
