For example, the '+' operator. Rust traits sez "gee, there's a +

string, or whatever idiot thing someone decided to use '+' for.
Number addition and string concatenation are monoid operations. In this
light, '+' for both makes perfect sense.
'+' is usually used to denote the operation of an abelian group.
The point is that '+' for string concatenation is no more of an 'idiot
thing' than '~'.
My point is that it is. String concatenation is not commutative.
