OK, I've almost got it working again except for one tiny thing (that
breaks everything)... #compilerClass no longer exists.  I've poked
around and all of the compiler indirection has been removed (i.e.
Compiler is hard-coded everywhere).  This completely breaks OMeta2 so
unless Juan would consider bringing this functionality back, it's
probably not going to work without essentially a rewrite.

... so that's why I gave up on it :-(
