Since the 'method_added' method itself is called from the context of
the class, is it perhaps sufficient to just call ns_override
directly? i.e.
def method_added(sym)
... # your existing code
ns_override sel
end

Excellent.
Earlier today Tim Burks noted that calling ns_override if there isn't
an existing ObjC method defined causes an exception (he found this
when switching a base-class implementation between Ruby and ObjC).
Arguably this is an exceptional case. I think that with the
method_added hook we can treat that problem as resolved too, since
people shouldn't need to use ns_override any more.
