Comment (by simonpj):

 I'm all for it -- go for it.  Obviously add some relevant notes etc.
 You'll still need it in `knownKeyNames`, though, since GHC uses it during
 zonking and elsewhere.

 I love the song but I'm missing the soundtrack.  You should put it up on
 Youtube with you singing it to a backing track :-)
