[swift-evolution] Should we incorporate bunches of new operators / micro-syntactic sugar?

Dear all,

That’s not ambitious but i think worth be explored.

What do you think for example of this Infix operator?
« =? »  allows to express optional assignments  in a very concise way.

// The `=? operator allows simplify optional assignements :
//  `a = b ?? a` can be written : `a =? b`
infix operator =?: AssignmentPrecedence

public func =?<T> ( left:inout T?, right: T? ){
    left = right ?? left

public func =?<T> ( left:inout T, right: T? ){
    left = right ?? left

Do you have such operators that you really use very often?

Best regards
