.... and even that maybe not so difficult... :]

When I added 5.2 support to my code, I realized I was _always_ using
load+setefenv in pairs (even when sometimes they were separated by
quite a bit of other code), although I never intentionally did so, and
that it wasn't hard to make sure the environment was available at
load-time and pass it in to load (5.1 load will just ignore it of
course).  Sometimes a little refactoring was required, but this tended
to make the code clearer anyway....
