Why is x not a delegate?
Because you didn't ask for one and it didn't have to be.
Just add the dele

Just add the delegate keyword to ask for one:
auto x = delegate(GdkEventButton* e

In gtkD one can use a lambda directly:
X.addOnButtonPress((GdkEventButton* e, Widget w) ...
but if I try move the lambda in to a variable so I can use it
with multiple handlers, I get an error:
// x is a function and does not work
auto x = (GdkEventButton* e, Widget w) ...
X.a
