Editors used with Scheme

[CPH%MIT-OZ@MIT-MC.ARPA]

Folks around here seem to use Emacs almost exclusively.  I think that
most people find it pretty adequate, although, not being familiar with
the Interlisp structure editor, I may not know what I'm missing.

Perhaps your Emacs is deficient?  You mentioned mocklisp, which leads
me to believe that you are using Gosling Emacs.  If you are using BSD
Unix, maybe you should try GNU Emacs, which is available free and is
the best Emacs there is (Stallman wrote it).  If you try that and
still find it lacking, then perhaps Emacs implementors should make
some changes.
