struct Point { int x; int y; }

void main ()
{
    Point p;

    mixin Foo!(p.x);               // works (prints "x" at compile time)

    mixin Foo!(Point.x);           // works (prints "x" at compile time)

    mixin Foo!(p.tupleof[0]);      // Error: expression (Point).x is not a
valid template value argument (but still prints "(Point).x" at compile time)

    mixin Foo!(Point.tupleof[0]);  // Error: expression (Point).x is not a
valid template value argument (but still prints "(Point).x" at compile time)
}

template Foo (alias a)
{
    pragma (msg, a.stringof);
}

Shouldn't p.x and p.tupleof[0] work the same way ?

tested on DMD 2.036
