Comment:

 This patch is important too:
 {{{
 commit 09b025eabf08044b67d047b970cd99add97e9d77
 Author: Simon Peyton Jones <simonpj at microsoft.com>
 Date:   Wed May 22 17:43:56 2013 +0100

     Wibbles to yesterday's "Simplify kind generalisation" patch

     In particular, in mkExport we must quantify over the kind
     variables mentioned in the kinds of the free type variables
