I recommend doing a literature search for papers by David Sandberg.
He's a young professor at Oregon State U. who built a compiler with
a freely redefinable syntax. The compiler ran at 2000 lines/minute on
a Vax, fast enough to be usable, I think. I remember it was possible
to define a "|x|" absolute value operator, and he demonstrated a header
file to make ";" statement delimiters optional. Operator precedence
was specifyable, pair by pair, but that would get huge in a real system.
