The easiest way to do a dynamic import is to build an
import statement and feed it into the exec statement.

On the other hand, I'd question why you actually want
the name in the global namespace of your module. Might
putting it in some kind of data structure be better for your
program logic? I don't know enough about your application
to tell, though.
