Ahh, I see.

print() is a method in python3 as well.

print() acts like a global function in ruby.  Kernel is "mixed into" the 
Object class, from which all objects inherit, which means any object can 
call the methods defined in Kernel.  And because the methods defined in 
Kernel are private, you cannot specify a receiver when calling the 
methods, and therefore calling a Kernel method looks like calling a 
global method in any other language.

In ruby, the name of a method is not a reference to the method.  Rather, 
the name of the method serves as a method call with no arguments.
