=item As a floating point number
The integer part would be the actual identifier. The fractional
part could encode some classification scheme.
Floating point numbers don't work this way. Suppose I

I'm leaning to splitting identifier from the classification.
A pure monotonically increasing integer would ensure the non-reuse.
And the classification scheme could evolve seperately.
Using numbers for the classification scheme would require a translation
table. So why not just use

PS Can this be merged with RFC 80, or do they need to live apart?
I believe they do. This portion can independently survive without
an exception mechanism. I'm only addressing the "what error did
I get". You are addressing the error handling
well, if it is only a string, why use . as the separator? use something
else like : and no one will try any fancy math tricks on it.
Agreed. I like :, it's a common separator.
Also, how about just $@-id? Shorter and I would argue the "unique_" is
really redundant (id's are usually unique,

I have listed some possiblities. But none of these are ideal.

Not really.
Consider: Chaim is an identifier. But not unique.

[stuff about exception numbering]
Hmm, I thought I saw another exception RFC pass by.
Yup, RFC 88, Tony Olekshy [EMAIL PROTECTED]
Could you two folks get together and hash this out.
RFC 88 goes to some trouble to seperate exception handling from
exception objects. It
