A representation of a single die.

It can be rolled using the roll() method, which will give a Roll result.

A Die object cannot change. Use the addition operators and the Dice class to represent more complex dice expressions.

A collection of Die objects and/or a modifier that can be rolled using the roll() method.

The properties of Dice objects are immutable; use the addition operators to combine them with other Die objects or modifiers. You can use compound assignment operators if you want, so long as you declare the Dice object as a var instead of a let constant.

A representation of a weighted die; i.e. a die whose sides do not necessarily have the same chance of being rolled.

The chances of specific rolls are passed using a Chances object. It is recommended to create the object separately, because it is easier to manipulate the Chances that way.
