You might find this interesting:
http://per.bothner.com/blog/2010/Q2-extensible-syntax/

This is an experimental intermediate step, creating a pseudo-Scheme
with infix, indentation. and parentheses uses purely for grouping.
If I wanted to design a complete new syntax, I would probably change
more, starting with some of the predefined keywords (including define).

If you're curious to play with it, just run Kawa with the --q2 flag.
There are some examples in the gnu/q2/testsuite directory of the
Kawa source distribution, though some of these test edge-cases
rather than recommended syntax.
