(I've re-posting here upon request from bearophile, who seems to like it :) )

I'd like to be able to use UFCS with fully qualified function names.

A typical use case is to disambiguate , as in the following case:

import std.path;
import std.string;
void main(){
    //Error: std.path.join()(const(char)[] p1, const(char)[] p2, const(char[])[] more...) at ... conflicts with std.string.join at ...
    auto a="".join("\n");
    //what I'd like to have:
    auto a="".(std.path.join)("\n");
}

note: the fact that std.path.join!().join is deprecated is irrelevant to this discussion.

Any chance this could be supported?

benefits:

avoids breaking UFCS chains
