Also, the "@" method already exists in the class Number... it's used to make
Point objects.

Special characters such as "@" can only be used in "binary" selectors (method
names), which always have one argument, and cannot include any alphanumeric
characters.  Examples: +, -, //, etc.

"Keyword" selectors such as "size:" can contain only alphanumeric characters.
