I believe that we need to concentrate first on the semantics of the
language and then be able to display data using different
conventions. And since code is data, this applies to code as well. I
favor a simple notation/syntax which purely reflects the semantics of
the language. Something like Lisp or Forth is good in this sense. And
then, if you are a mathematician and you are used to dealing with
Fortran notation, we can easily build an editor to view and edit
formulas using your prefered notation.

Fully agreed too. See what I said above.
Happy new year to all, Laurent
