https://stackoverflow.com/questions/4294485/how-do-i-reference-a-function- in-ruby Especially this answer, which is worth reading: https://stackoverflow.com/a/4294660 As best I can interpret it, Ruby starts with the premise that functions and methods are NOT first-class values -- or rather, since Ruby functions are actually methods of Object, there are no functions, only methods, and they are not first-class values. obj.method, despite superficially looking like the same as Ruby's dot syntax for attribute access, actually is syntax for calling the method. In practice, that's not as restrictive as it may seem. Where Python would pass a function object to a higher-order function, Ruby would usually pass an anonymous block or possibly a Proc. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
