I believe it was things like "+" and "-" for set union and subtraction, etc.
That, or &, |, and ^, by analogy with bitwise operators. It definitely came up
during the SetAlgebra discussions.
Another thread I guess I didn’t follow closely enough. I think I agree with
avoiding using unconventional operators for operations which already have
conventional operators associated with them. Maybe someday it will be easy
enough to type unicode operators that it might be reasonable to think about
using them.
Yes, there is precedent in other languages:
Ceylon uses "&" for type intersection (any<>) and "|" for type union (one<>),
see http://ceylon-lang.org/documentation/1.2/tour/types/.
TypeScript does the same (see
https://www.typescriptlang.org/docs/handbook/advanced-types.html).
