perl module for sets of ordered constants like enums in C
The enum module defines a set of symbolic constants with ordered numeric values ala C enum types.
It is now capable of creating ordered bitmask constants as well. See the BITMASKS section in the documentation for details.
What are they good for? Typical uses would be for giving mnemonic names to indexes of arrays. Such arrays might be a list of months, days, or a return value index from a function such as localtime().
