Test case:
----
import std.typecons, std.range;
struct S {
    void put(int[] a){}
    void put(int   n){}
}
void main() {
    S s;
    put(s,  1);     // OK
    put(s, [1]);    // OK

    auto rs = RefCounted!S();
    put(rs,  1);    // doesn't work
    put(rs, [1]);   // doesn't work
}
----

To fix this issue, both Phobos and dmd needs to be fixed.
- std.traits.hasMembers doesn't see the members through alias this.
- There is no way to check whether a type T has a member xxx or not, while
avoiding UFCS.

I've conceived following technique, but doesn't work with current dmd.

struct T { void put(){} }
alias T.put X;   // Type.member doesn't test UFCS,
                 // but getting symbol of xxx would work!
struct S { T t; alias t this; }
alias S.put X;   // Getting symbol through alias this doesn't work...

I think we need to fix bug 4617.
