[swift-evolution] [Proposal] Refining Identifier and Operator Symbology

[Jonathan S. Shapiro]

Quick poll as a sanity check on a possible alternative for operators:

If we admitted [:Sm:] and [:So:] and the traditional ASCII operator
characters, would that cover the things that people currently feel
passionate about? That would almost certainly be compliant with UAX31 once
it settles, and I *think* it covers all of the cases people have raised
here.

Useful links if you want to check:

[:Sm:]  Symbol, Math

[:So:]   Symbol, Other
<http://www.fileformat.info/info/unicode/category/So/list.htm>


Having looked it over, I'm concerned about including [:Sk:] in UAX31
operators, and I'm probably going to recommend in the UAX31 discussion that
we shouldn't do so.
