[Haskell-cafe] How unique is Unique

[Emil Axelsson]

Hello!

Lacking a proper blog, I've written some notes about Data.Unique here:

   http://community.haskell.org/~emax/darcs/MoreUnique/

This describes a real problem that makes Data.Unique unsuitable for 
implementing observable sharing.

The document also proposes a solution that uses time stamps to generate 
symbols that are "more unique".

Does anyone have any comments on the proposed solution? Are there any 
alternatives available?

Thanks!
