Description

Data.Unique should be able to be used with Data.Dynamic.

Timescale for consideration: Until September 7, 2008.

The library submission procedures say

If the changes update Haddoc [sic] documentation, also attach the resulting Haddock-generated pages.

Haddock fails on the file because of existing CPP commands.

Ganesh Sittampalam pointed out that this allows Data.Unique to break when using hs-plugins, due to some hackery choices by hs-plugins and Data.Unique. (Ganesh's message, mirror)

I'm trying to get more details.

After reading some of the cafe thread on this issue ("Subject: Top Level <-"), I'm afraid I don't have the time needed to come up with a thorough answer to whether or not this is dangerous.
