I recently stopped using enums after reading this:
http://www.commandprompt.com/blogs/joshua_drake/2009/01/fk_check_enum_or_domain_that_is_the_question/
Using a foreign key to a single column table is pretty much as fast as
an enum, is supported by most (all?) third party libraries, and avoids
all the problems associated with enums.
I guess the downside is the foreign key will take up more disk space,
but that isn't an issue for me.
