Well, although I can't really see how an underscore is either better or worse
than a period, the main problem with this approach is twofold:

1. It adds another function call on top of the function already written in the
include file. In loops, this will slow things down considerably. There's also
the extra typing. More chance for errors.

2. Eliminating the "attempt to redefine" error when you have two
globals with the same name, which would be necessary in order for the above to
work, could cause some interesting problems for people who are using existing
libraries. (No more warnings about duplicated variable or function names)

Ideally, the "dot" notation (whatever) shouldn't be required, except in cases
where there is a confirmed conflict. That would let existing code run without
changes.

Perhaps an error message is all that's needed.
  "foo" is defined in button.e
  "foo" is defined in other.e
when there's any question. When you get the error, add the appropriate prefix.
