Feature request: Add support for custom operators

Language Design
1

Hello mates!

In Swift it’s possible to create custom operators like this:

prefix operator |
postfix operator |
infix operator | : AdditionPrecedence

But in Kotlin you can only use predefined set or letters like ‘I’ for operators.

It will be incredible if you add support for any operators in the future :smiling_face:

So it will be possible to make the translation of ‘The Wand: Declarative programming language for error-free coding’ also to Kotlin. And we will support all actual mobile ecosystems.

This might be unlikely to be added.
In the meantime though, you might wanna check out my IntelliJ Plugin that uses folding regions to have the code display as if those were operators.
For instance:

@Pretty("~")
@Prefix("", "")
fun inv(foo: Foo)

@Postfix("", "")
val Int.c

@Pretty("&")
infix fun Int.and(other: Int)

inv(foo) // Displays as ~foo
5.c // Displays as 5c
5 and 10 // displays as 5 & 10
