Chris - I really appreciate that you take the time to entertain & respond to proposals.

I completely agree with that proposal being rejected. I am not asking to replace existing language grammar. My desire is for the support of alphabetical characters for custom operators to allow third party libraries to have their own unique grammar.

And I completely agree that function/method syntax can easily suffice for normal circumstances. Just trying to see how far Swift can be stretched.
