[swift-evolution] Name disambiguation of computed property/function with same type defined in extensions

[Vladimir.S]

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()
