Also, since I drank three cups of coffee this afternoon, and it's raining, I added two new sets of syntax to make it more feature complete: the ".." operator and the "-" operator, both for picking numbers within a range.
"1..10" picks a number from the set of 1,2,3,...,8,9,10.
"1-10" picks a number from the set of 2,3,4,...,8,9. (excluding the upper and lower boundaries).
Similar to the "1d10" types of rolls, but a little easier on the mind if you're having to repeatedly do things like "sum up 10 different dice."
