Re: [Issue 4042] Unable to instantiate a struct template.

[wrzosk]

The test case compiles when exec method definition is moved down:
template isQObjectType(T)
{
    enum isQObjectType = is(T.__isQObjectType);
}

template QTypeInfo(T)
{
    static if (!isQObjectType!T)
    {
        enum size = T.sizeof;
    }
}

struct QList(T)
{
    alias QTypeInfo!T TI;
    int x;

    void foo()
    {
        x++;
    }
}


interface IQGraphicsItem
{
}
void exec(QList!(QAction) actions) {}

abstract class QGraphicsObject : IQGraphicsItem
{
}

class QGraphicsWidget : QGraphicsObject
{
}

class QAction
{
    final void associatedGraphicsWidgets(QList!(QGraphicsWidget) a)
    {
        QList!(QGraphicsWidget) x;
    }
}

void main()
{
}
