i dunno ... that seems like it would really kill the utility of a field for a
lot of use cases – if it had that kind of limitation, i would just use an "int"
field an managing the mappings myself so id always know i could add/remove
(EDIT) fields values w/o needing to reindex.

This isnt really going to work here, because the idea is you want to assign
sort order (not just values mapped to ints). If you want to rename a label,
thats fine, but you cant really change the sort order without reindexing.

> We have encountered a use case in our system where we have a few fields
> (Severity. Risk etc) with a closed set of values, where the sort order for
> these values is pre-determined but not lexicographic (Critical is higher than
> High). Generically this is very close to how enums work.
> To implement, I have prototyped a new type of field: EnumField where the
> inputs are a closed predefined set of strings in a special configuration
> file (similar to currency.xml).
> The code is based on 4.2.1.
