Hm... well, I guess the confusion is that we're talking about having an
"out" or "inout" parameter which *isn't* pass-by-reference. I suppose if
you stop to think that Javascript doesn't have pass-by-reference then
that would be obvious, but presumably the corresponding methods in C++
and C# *would* use "GtkRequisition&" / "out Gtk.Requisition", and so
assigning to request like above in those languages *would* work. So
again, this is an argument for doing out params as return values like
now, rather than as sort-of-references.
