Overview

Thank youn my dear Proxy, for sending me all the information I, the clever guy, who is having all the fun, will make best use of it by being an extremly, yes I said extremly clever callable object representing the methods or instance methods represented by the calls to ‘Object#fn` or `Module#fm`. Did I tell you yet? It is sooooo out not be functional…
