Comment:

 When checking I noticed that the ChristmasTree package had problems
 compiling with the newer versions of GHC. I updated the package by adding
 some type annotations, and upgrading the cabal file.

 The fact that we did not get complaints thus far probably indicates that
 the problem is not perceived as a severe one by most users. I have no idea
 how many actually rely on this package or this technology.

 It would be nice if hackage would inform maintains about packages becoming
 obsolete due to upgrades of GHC or of packages it depends on, but that is
 another issue.
