Enumerated Scalar

[Mike Stephens]

As a one time Pascal programmer - does Ruby have the concept of an
enumerated scalar? It seems to have enumerations but I can't see a
standard method that recognizes inate ordering eg EObj.next, EObj < FObj
etc

There is definitively nothing built in. You have to create this
yourself or use one of the libs out there that implement enums.

Also, often Symbols are used to represent fixed values.
