Apart from C-like languages like C++, Objective C, C# and others with 
objects :-)

Actually in this specific instance, what seems to be tripping you up is 
not the *object oriented* flavour of the code, but the *functional 
programming* flavour of the code, specifically that functions are values 
at all. (Whether they are "objects" or not is not very important.)

In this case, it isn't *much* functional programming. It is just the 
idea that functions are values, just like strings and lists and floats.
