[swift-evolution] Request to add middle dot (U+00B7) as operator character?

Although I would personally never, ever want to do this, I see no reason why this character shouldn’t be allowed for an operator.

The question is: if we are to touch this are and extend the Unicode ranges of characters allowed for operators, what else is missing? A wider proposal to fill in the blanks would probably make sense.

FWIW, we have U+00B6 (¶) already defined as an operator, this would extend its range by one.
