I think this was based on the "the current module is part of the
environment, but local-eval does not change (current-module)" mantra
which I interpreted in a confused manner. The interesting thing is that
it is the _lexically_ current module that is part of the environment,
and inside of local-eval, this may well differ from the _actually_
current module as given by (current-module).
