FWIW I don't like the variant with 'from' keyword. Such syntax is too
verbose for me, this syntax requires braces, I need to parse whole contents
between braces to find out what is going here, we don't use words to
represent hierarchy i.e. when calling methods/props of instance or
referencing nested types (Type1.Type2).
IMO the best solution will be '::' as separator, so
("hello swift”.module() from ModuleA)
will be :
"hello swift”.ModuleA::module()

I’m thinking I’ll just go ahead and create a formal proposal with this:
Given
ModuleA
extension String {
public func module() -> String {
return "ModuleA"
}
}
ModuleB
extension String {
public func module() -> String {
return "ModuleB"
}
}
Problem
ModuleC
import ModuleA
import ModuleB
let module = "hello swift”.module() // ambiguous
Proposal
ModuleC
import ModuleA
import ModuleB
let moduleA = ("hello swift”.module() from ModuleA)
print(moduleA) // prints "ModuleA"
let moduleB = ("hello swift”.module() from ModuleB)
print(moduleB) // prints "ModuleB"
let chainingExample = ("hello swift”.module() from ModuleB).uppercased()
print(chainingExample) // prints "MODULEB"
