           Summary: ref binds to rvalues of user-defined types
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: andrei@metalanguage.com


struct Struct {}
alias Struct T;
//alias int T;

T fun() { return T(); }
void gun(ref T) {}
void main()
{
    gun(fun);
}

The code compiles and it shouldn't. ref should never bind to rvalues. Currently indeed it doesn't bind to rvalues of built-in type (e.g. if the alias above is switched from Struct to int the code won't compile).

Furthermore, adding this overload should make the code work:

void gun(T) {}

Currently adding the overload results in the error message:

function test.gun called with argument types:
        (Struct)
matches both:
        test.gun(ref Struct _param_0)
and:
        test.gun(Struct _param_0)
