Subject: Re: [PHP-DEV] [RFC] Enum proposal (yet another)
From: eitan@mosenkis.net (Eitan Mosenkis)

I think that your proposal looks good, but I'd like to suggest a few
changes. First of all, I'd like to see the association with integers
removed. An enum instance shouldn't just be a name for an integer, it
should be more like a singleton instance of a special kind of class
that can only ever have a predefined set of named instances. There
should be no value associated with it.

Secondly, there already exists the capacity for arbitrary classes to
be used in foreach and count you just have to implement Iterator and
Countable. Other interfaces that all enums might want to implement
automatically are ArrayAccess and Serializable. This would just
require the enum itself to be an object (maybe of type enum or
something) such that it can implement the relevant methods.
