Comment (by simonpj):

 I'm quite reluctant to duplicate all that tidying machinery. Moreover, we
 need to pretty-print `IfaceDecl`s anyway, so this is just duplicating
 that. If there isn't enough information in `IfaceSyn`, maybe we should add
 a little more. For Gergo's point I was going to add an extra constructor
 to `IfaceType`, corresponding to `=>`, for example.  Easy; and will
 improve the output from `--show-iface`.

 So by all means go ahead, and I will look, but I'm advertising that my
 instinct is still to take the approach I outlined.

 Simon
