They don't both always give the same result. "." is the message operator and
"::" is the scoping operator. In the case of methods, they both work the
same, but in the case of constants, you will get an "undefined method
"CONSTANT"" if you use ".".

So explicit scoping / getting nested constants, you have to use ::

For class methods, you can use either. I prefer "."
