For consistency use ".", for uniformity with other languages use
"::".  Historically Foo::foo() notation was introduced for those who
said that could be more understandable for C++ or Java people.

For my own preference, I use "." since that consistent in Ruby ---
in Foo.foo, receiver is Foo itself --- and "::" notation always needs
() if method name is capitalized.

# Well, capitalized name of class methods also out of my preference....

    > ruby
    class Foo; def self.foo; p :foo; end; end
    Foo.foo
    Foo::foo
    :foo
    :foo
    > ruby
    class Foo; def self.Bar; p :bar; end; end
    Foo.Bar
    Foo::Bar
    :bar
    -:3: uninitialized constant Foo::Bar (NameError)
