Extension methods for non-nominal types

@Jens

If you can tolerate a postfix operator like eg • , then you can extend (an "invisible" wrapper of) any type and write

Sure a lot of stuff can be tagged on with custom operators and/or wrappers; and Swift's history is littered with many examples including e.g. this more recent one for turning a keypath into a function .

Plus I can essentially use custom generic operators in Swift to mirror the same outcome for both nominal and non-nominal types, but extensions are restricted to only nominal. Seems such a pity, because I can imagine not everyone is crazy about interspersing their code with custom operators.
