I started working on this, but had to put it aside for awhile. My hang up
were some VM crashes with recursion (I suspect this was due to deeply
recusive blocks). If there are people interested in a coordinated effort,
please drop me a note via PRIVATE email.

As for exceptions, a lot depends on what you want. For porting, one needs
an exception system which emulates that of the thing which you port (how's
*that* for a stilted sentence!). David Farber posted to the list what
appears (so far in my experience) a solid port of (to quote his message):

(For the record, Dave, this is *very* useful! Thanks.)

An aside: things do work there way into the "core distribution"--the
Pluggable Web Server is a good example.

Code first, coordinate later ;) Right now that's not a bad principle.
