--- Comment #1 from Nick Treleaven <nick at geany.org> ---
Reduced with commented edit:

class Base
{
    size_t classSize(this This)()
    {
        pragma(msg, This);
        return This.sizeof;
    }
}

class Derived : Base
{
    void foo()
    {
        classSize();  // added ()
    }
}

Error: template `templatethisparam.Base.classSize` cannot deduce function from
argument types `!()()`, candidates are:
       `templatethisparam.Base.classSize(this This)()`
