Comment (by archblob):

 I didn't really consider the parsing aspect on the lists although every
 time I added another abstraction I wondered how much bigger and slower the
 interface files will get. I'll be changing the representation of
 {{{IfaceTcArg}}} as we discussed, and I'll also do the necessary
 measurements of everything I add on top of the existing representation.

 I also added another field to {{{IfaceClosedSynFamilyTyCon}}} so now it's
 represented like  {{{IfaceClosedSynFamilyTyCon IfExtName
 [IfaceAxBranch]}}} in order to print closed type families the right way.
