Very interesting module. I will play with it in the newar future :)

| LIMITATIONS
|      A few limitations exist in the current version. All of them could be
|      removed in future versions - especially with your help. =)

I hope you count feedback as such!

|    No continuous attributes
|
|      In the current implementation, only discrete-valued attributes are
|      supported. This means that an attribute like "temperature" can have
|      values like "cool", "medium", and "hot", but using actual
| temperatures
|      like 87 or 62.3 is not going to work.

I guess you could have a look at Robert Rothenbergs Tie::RangeHash module.
It should help a lot for numerics. Maybe you can just recommend its use in
the docs of your module.
