When you describe a class method, we can use the Ruby call notation,
so we can say "call Array.new to create an array".

When you're describing an instance method, however, you can't
conveniently use the calling sequence, as this will involve some
arbitrary object:  anArray.join. To get around this, the convention
has grown that Array#join refers to an instance method 'join' in
'Array'. In the book, we use this in inline text, but use an
example-based syntax in the reference section.


Ain't ideal.
