Rethink Operators - make them more flexible with ability to define all properties of operators

[Suminda Dharmasena]

Hello,

Wondering if you can re think operators within Dotty where developer has finer control over all properties of an operator. I.e., can specify:

• Symbol 
• tertiary and higher arity the placement of operator symbols and operands
• Position of the operator
• prefix, 
• infix or 
• postfix
  
• Associativity
  
• Precedence
  
• etc.

Perhaps you can borrow from Swift (https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/AdvancedOperators.html#//apple_ref/doc/uid/TP40014097-CH27-ID46) Only thing that swift does not define is how symbols interact with the arity beyond tertiary.

I second this question.

Outside Scala there exist families of operators that may have any aritiy, while not being associative.

E.g. SubScript has a composition operator & for expressing parallel merge:

 break & x  & y   would be an empty process

[break & x] & y   would be equivalent to process y
