https://web.archive.org/web/20140107054455/http://yinwang0.wordpress.com/2013/12/24/oop/ is everything an object ? 
In some languages such as Scala or Python, functions are also treated as objects. But actually they just wrapped the functions into an object, give them some name such as “apply” or “__call__”, so that when the objects are “invoked” you know which functions to call. But putting a function into an object doesn’t really mean that functions are also objects, just like inviting friends to your house doesn’t make them your family.
