struct T11955(T...) { T field; alias field this; }

alias X11955 = uint;

struct S11955
{
    enum empty = false;
    T11955!(uint, uint) front;
    void popFront() {}
}

void main()
{
    foreach(X11955 i, v; S11955()) {}
}

The argument type 'X11955' has not had semantic run on it, so checking the
implicit conversion from agg.front[0] to it fails.
