For better interfacing to other programming languages, the symbols of enum
types can be assigned an explicit ordinal value. However, the ordinal values
must be in ascending order. A symbol whose ordinal value is not
explicitly given is assigned the value of the previous symbol + 1.
An explicit ordered enum can have *holes*:

Enumerations without holes, integer types, ``char`` and ``bool`` (and
Enumerations, integer types, ``char`` and ``bool`` (and
subranges) are called ordinal types. Ordinal types have quite
a few special operations:
