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:)

What happens when you need the backticks for the function name itself? We can't
nest them.
func `class`() {}
`class`() // Function call.
`class()` // Function reference.
