          Issue ID: 13374
           Summary: Wrong template overload resolution when passing
                    function to alias/string parameter
           Product: D
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: regression
          Priority: P1
         Component: DMD

///// test.d /////
void f(alias a)()
{
}

void f(string s)()
{
}

void x(int i) {}

void main()
{
    f!x();
}
//////////////////

Compiler attempts to evaluate x despite that it's impossible and its return type is not convertible to a string. But even if x took no arguments and returned a string, there needs to be a way to pass the function by alias, not by its evaluation result.
