I know that, but it’s highly incidental to my point, as I’m sure you’re aware. It’s obviously true that (foo - bar) is legal, as is (foo-bar), as is (foo - bar + bash), as is (foo-bar + bash) and so on, but they’re still much less likely to be mistaken for foo-bar in an infix language.

I’m sure you knew perfectly well that I meant you never type foo - bar meaning foo subtract bar :-)
