A final proposal for await syntax

[phil_opp]

@kornel made a really good point in another thread that the dot operator can already be seen as syntactic sugar for the (prefix) universal function calling syntax:

Idea: universal pipelining (a.k.a. making @await generic)

We have universal function calling syntax, so: instance.method() is equivalent to Type::method(instance). The D language (and to a degree, JS and Python too) goes as far as making all functions equally usable with both syntaxes. IMHO that’s pretty elegant. So I see . not as related to the type, but as a syntax sugar that moves the first function argument to the prefix position. Macros already pretend to be function-like. Therefore, making macro!(expr) and expr.macro!() equal would seem like …

Supporting both await expr and expr.await seems consistent with this model.
