Range Token
Brought to you by:

The range token will be "..". Range expressions will be derived from range tokens. The range token will be treated like an operator. A range might look like 1..20 or 0..-13. Ranges will be printable, and you will be able to use them in the future in functions and with variables; i.e. you can set a variable to contain a range, then use it in an expression symbolically.
I'm going to implement this next.
