I think excluding specific methods would be unusual in practice. Of
course, I'm of the opinion that traits are a solution in search of a
problem to begin with, so take my opinions with a grain of salt.

Anyway, I suppose I could add an option where it simply discards dup's
dynamically when a module is included:

class X
   use ModA, :no_override
end

That would be interpreted as "include all methods unless already
defined".
