FWIW, I want to point out the enum<->string conversion macros which Neil 
Williams posted to pilot-link-devel in April/May of 2005, including this link 
to a related thread:


These require a macro-ized marking up of enums, and would then allow to store 
its values as string.

I guess at least *someone* will find this helpful for something..
