[swift-evolution] Pitch: Compound name `foo(:)` for nullary functions

[Vladimir.S]

FWIW, I do think the foo(_) is the best variant. For me it means "no 
argument label AND no argument at all, as there is no `:` in it".
foo(_:) means "no argument label BUT one argument". etc.
As for `class()` IMO it is too cryptic. class(_) is more clear about what 
it *is*(because of _ as parameters, that symbol is not used when we call 
the func but used when we define a reference to it, like class(_:), 
class(_:something:)
