Hmmm: If infix:xor returns Scalar.boolean, there might be hope. This would involve
returning something like a.or.b but a.xor.b.

Re: | vs Â
Boggle! Who let that slip in?
I kind of got the impression he was asking about e.g., ??! or some such, a la ANSI C.
(In the same vein as << for Â, etc.)
But no, it's far worse: every keyboard that is capable of generating '|' is labeled
incorrectly. How's that for the principle of least surprise?
It's like the old Far Side cartoon showing "Ed's Dingoes" right next to "Martha's Day
Care" -- trouble waiting to happen. Let's pray nobody uses Â...

PS:
S3 appears inconsistent WRT the . operator and hyperoperation. One example uses
("f","oo","bar")Â.Âlength,
while elsewhere you have @objectsÂ.run();
Comment?
