1.15 Enums

Enum

enum is a master keyword, it is used to create a enum definition.
An enum is a collection of named constants.
Example of a simple enum definition:

enum Color {
    RED,
    GREEN,
    BLUE
}

do say (Color->RED) // 0
do say (Color->GREEN) // 1
do say (Color->BLUE) // 2

The syntax for creating a enum is as follows:

1. After the enum keyword, you write the name of the enum.
2. A enum body, this is enclosed in curly braces.
3. Each constant is separated by a comma.
4. Each constant is assigned a value, starting at 0.

Setting specific values

You can also set specific values for each constant.
Example of a enum definition with specific values:

enum Color {
    RED = 1,
    GREEN = 2,
    BLUE = 4
}

do say (Color->RED) // 1
do say (Color->GREEN) // 2
do say (Color->BLUE) // 4

You can mix match, it'll start counting again from the last value.
Example of a enum definition with mixed values:

enum Color {
    RED = 5,
    GREEN,
    BLUE = 10
}

do say (Color->RED) // 5
do say (Color->GREEN) // 6, because RED is 5
do say (Color->BLUE) // 10
