The API Function.defineOperator(symbol, type1, type2) would be
perfect to support this. However I assume this is not the intention?
Is there any openness to supporting user defined infix operators or
at least an extended set similar to Python's PEP 225 proposal
(http://www.python.org/dev/peps/pep-0225/)?
I'm not proposing syntactically novel operator extension. That is hard
in a C-like language, but doable with enough work. It would be a
separate proposal on top.
Just to set expectations, this won't be done quickly. As I understand
it, http://sweetjs.org/ (macros for JS, Tim Disney's baby) needs to come
along farther, and tackle "enforestation", before new infix operators
support is anywhere near a strawman for an ECMA-262 future edition.
