Pyret Programming Language

Yes, that would be:

    method = o.method(:my_method)
    method.call(5)
    # or method[5], or method.(5)

If you really want a "function" that you can call with parens:

   Kernel.define_method(:method_as_fun, &method)

(Definitely don't do that last bit in a real project...)

And before someone criticizes Ruby for being inconsistent in how the method is called, Ruby isn't a callable oriented language [1]. The common case is calling methods, so the fact that you need to say `.call(5)` both makes it more consistent and makes real code more concise, especially when making DSLs where chaining is really useful.
