The term "monkey patching" describes injecting additional methods into
a class whose implementation you don't control. If done without care,
this is dangerous; the problematic case arises when:
* You add a method to a class;
* A newer version of the monkey-patched class adds another method of
the same name
* And uses that new method in some other part of its own
implementation.
.
ex::monkeypatched lets you do this sort of monkey-patching safely:
before it injects a method into the target class, it checks whether the
class already has a method of the same name. If it finds such a
method, it throws an exception (at compile-time with respect to the
code that does the injection).
