In general, the goal would be "scoped monkey patching" since I
sometimes want to monkey patch, say, Float, but only within my own
lib.

My first thought at how to implement it would be

namespace A do
  class Float
     def my_method
      "%f" % self
     end
  end

end

and then later

namespace A do
   3.3.my_method # this would work by, on method_missing, search for
method in A::Float
end

So I suppose this is about the same as the proposal discussed in 2009

Now how it to actually *accomplish* this I have no idea, if it's block
syntax.  If it's per-file selector, then you could use method_missing
to lookup any namespaces and see if it should be called there.  Both
feel a bit kludgey, so I'm not sure.
