One way to do what you're looking to do, is to write in top.ml:

module Bottom = Bottom

This will essentially re-export Bottom in Top.  Unfortunately, this
requires that you link bottom.cmo in with your code, which causes
Bottom to be visible at the top level.

A similar effect can be obtained with the -pack flag:

ocamlc -pack top.ml bottom.ml foo.cmo

Top and Bottom can now be referenced as Foo.Top and Foo.Bottom, and
only foo.cmo needs to be linked.  I know this isn't exactly what
you're looking for, but it might do the trick just the same.
