Yes (although I cannot find a link right now). Some people argue that,
as two different VMs is wrong, we should not try to disguise the
symptoms. Lua 5.2 has a verification system that should raise an
error as soon as any library with a wrong VM is loaded.

(Oops, except that there seems to be a little bug there. The check
is only being done in a deprecated function ;)
