Comment:

 Here's the patch:
 {{{
 Tue Dec 30 16:44:32 GMT 2008  simonpj at microsoft.com
   * Avoid nasty name clash with associated data types (fixes Trac #2888)

   The main bug was in TcHsType; see Note [Avoid name clashes for
   associated data types].  However I did a bit of re-factoring while
   I was about it.
 }}}
 Not in the commit message (accidentally) but I added a test for empty type
 indices.  Currently it's an error not a warning.

 Pls merge

 Simon
