[swift-evolution] Proposal: x == 2 should not be a valid statement

[David Waite]

Won’t that conflict with the existing use of “is” as a keyword for type tests?

You know, if we proposed changing ‘ == ‘ to ‘ = ‘ and ‘ = ‘ to ‘ := ‘ it would break all existing code, plus *really* stir up the “Colon vs Equals” thread.

I’m of course  -1 on changing around equality, equivalence and assignment syntax without strong justification.
