The problem with cons/car/cdr is that they're fundemental operations.
Graham *has* learned from perl, and is receptive to the idea that
fundemental operators should be huffman encoded (lambda - fn). It
would be easy to simply rename car/cdr to first/rest, but that loses

Yes, languages should now use IMCC as their target. Basically, they
generate IMCC instructions without regards for optimization and such so that
only a lexer/parser is needed. Take a look at the bf and ook languages for
