Enums

Enums are a lists of constant values, either strings or numbers. By default an enum is of value type int and each case will have a incremented value starting at 0. To get the value associated with a case, use the value property.

enum Natural {
    zero,
    one,
    two,
}

Natural.zero.value == 0;

If the enum's value type is not int, it must be specified between parentheses after the enum keyword.

enum<str> Country {
    usa = "United States of America",
    uk = "United Kingdoms",
    fr = "France",
}

The value type must be one of: str, int, double, pat, rg, ud, void.

To get the enum case from its value, you can call the enum like a function with the value as argument.

var country = Country("France");
country == Country.fr;

When the value type is str, you can omit case values which will be the same as the case name.

enum<str> Locale {
    fr,
    it,
    en,
}

Locale.en.value == "en";

If one case value is specified all cases must also have a value.
