Not commenting on whether this issue should be fixed or not:  I would
like to point out that it is a common implementation trick in the Lisp
world.  Other languages have solved similar issues by either
  (1) totally ignoring it (C, C++)
  (2) introducing elaborate forms of packaging, versioning,
      etc. (Perl, Java, etc.)

None seems to have a perfect simple answer.


As for the C world, you probably heard of `DLL hell', or
LD_LIBRARY_PATH  or RPATH (and why they are all considered hamrful).

Obvious free advice: give unique names to your files.  Yes, it can lead
to non-obvious situations.  Pick your poison.
