It's method_chain() that's broken, it should be able to safely chain method 
chains, but I didn't write a test that exercised the case where a callable 
is a chain with a 'next_method'.  I've added a test case now and fixed it.

Thanks for all the useful bug reports; I haven't made any real use of 
before/after/around stuff yet myself, just the tests.
