[swift-evolution] Proposal: change infix operator attributes syntax to be more consistent with the rest of the language

[Erica Sadun]

I like this approach too BUT my only concern is how long it takes to get to the actual name. 
I know I probably hate this already (give me time to sleep on it) and I'm not wedded to the 
approach, but I'd like to see the operator move left for readability so that it's more like a 
func declaration:

operator +=(infix, associativity: right, precedence: 90, assignment) 
operator -(prefix)
operator !(postfix)

Usually, a bunch of parameters modifying a declaration would go in a parenthesized list after the particular keyword they modified, and in this case, `associativity` and `precedence` (and probably `assignment` too, though I don't know for sure since it's not documented) are only valid on an infix operator. That would suggest:
