A partial solution is for ALAN to re-install DEFSHARP so that any file
which thinks it needs this security could do its own local definition
for "#:", and we could propogate a general prohibition for using "#:"
for anything else until the question has been fully settled. (By the bye,
I'd really like to see DEFSHARP be defaulty loaded - it is now with the
maclisp SHARPM file).
I really don't see why a special form for defining sharpsign macro
characters is any better than SETSYNTAX-SHARP-MACRO which is a
function that can be called to set up a new sharpsign macro. When I
originally wrote DEFSHARP for my own sharpsign macro in MacLisp, it
was intended to be an internal convience macro since I was going to be
defining a lot of sharpsign macros at the same time. I had no
intention that it should escape beyond the bounds of that file.
