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?
This has nothing to do with Unique, you are simply using unsafePerformIO in an unsafe way. It is called unsafePerformIO for a reason :-) Cheers, Simon
