The responsible thing when you use `method_missing` is to define `respond_to` to indicate whether an object responds to a particular method. This alleviates the "is a method available" issue because you can just ask the object "Do you respond to :method_I_want_to_call?", and it will correctly inform you it does or does not. This kind of discoverability is one of the things I miss when I'm working in Javascript/TS as I have been recently - sure you can check the .method_name property to see if it's a function and then execute it but it doesn't feel as nice. E.g. def method_missing(name, \*args) if name =~ /^has_/ has(name, *args) end super end def respond_to(name) if name =~ /^has_/ return true end super end
