Description
Hi,
due to a discussion on IRC I have noticed that the ,m command still does not work as desired. For example, I would expect this to work:

This is not a bug: in compiled modules, unexported identifiers do truly not exist: they are hidden and effectively optimized away, stored in some location only known to the compiler. Unexported bindings can be inlined and removed completely in many cases. So switching into the module can not make them magically appear again. This is different when using interpreted code: here even hidden bindings still exist, even if hidden. If you think this is an inconsistency between compiled and interpreted code, you are right. But the compiler must be able to remove non-exported bindings, for performance reasons.
