Cmm comments are not Haddock comments---should this change?

The definitions of the Cmm data structures are richly commented in the source code, but the comments are not Haddock comments, so the information doesn't make it into the Haddock documentation. As I refresh my memory about Cmm, I'm thinking of converting the existing comments to Haddock comments. The only downside I can think of is that the Haddock pages may appear more cluttered. Is there any reason I should refrain? Norman
