If you are going to compile down to something other than straight Erlang
then the best target is Core erlang. It a pure relatively simple and
standard functional language which is used inside the compiler. The AST is
defined by a set of records and there are tools to read/check/print it. As
far as I know there is nothing *legal* you can do in the BEAM code which you
can't do in Core. Also you have the benefit of not being forced to modify
your compiler as the BEAM engine is improved. If I remember correctly HIPA
also uses Core for one pass in its compiler. Someone who knows can comment.

This is what I am doing for my LISP front-end to Erlang. Soon to be ready.
