We could store this as a Rational, say, instead of a String. However, we will never need to use its value for anything. Indeed, the only thing we will be doing with it is turning it back into a string at some stage, so we might as well cut out the middle man and store it directly like this.

Color to use for numbers.

Parses integers and reals, like 123 and 45.67. To be more precise, any numbers matching the regex \d+(\.\d+)? should get parsed by this function.

>>> parseNumberLit '3' "456hello world []"
("3456","hello world []")

>>> parseNumberLit '0' ".12399880 foobar"
("0.12399880"," foobar")
