So that instead, it passed the UnboundMethod directly to
define_method. This does what I want and seems reasonable. Please
let me know if there are problems, otherwise, I'm a happy camper now.

def reveal(name)
unbound_method = find_hidden_method(name)
fail "Don't know how to reveal method '#{name}'" unless unbound_method
define_method(name, unbound_method)
end
