Currently, "infix" is not required/allowed on an operator function
definition, but "prefix" and "postfix" are:
prefix operator ^^ {} // valid
postfix operator ^^ {} // valid
infix operator ^^ {} // valid
prefix func ^^(operand: Int) {} // valid
postfix func ^^(operand: Int) {} // valid
infix func ^^(lhs: Int, rhs: Int) {} // *error: *'infix' modifier is
not required or allowed on func declarations
func ^^(lhs: Int, rhs: Int) {} // valid
It seems like this was removed because it can be inferred from the number
of arguments (
https://github.com/apple/swift/commit/3ad9c58c18f0331444114e2eae3e772e702c326f).
But IMO the inconsistency from other operator function decls/defs is
jarring.
How does everyone feel about reinstating the "infix" modifier on functoins?
(It was removed before the open-source release and the advent of
swift-evolution, so I thought it'd be worth a public review.)
