HEAD build fails on compiling haddoc

[Simon Peyton Jones]

I pushed a change to Haddock, and a change to GHC.  They should match up.  Did you do ./sync-all pull?

I may have screwed up.  I sent a long message to ghc-devs this morning explaining what I did.  Maybe some guru can help.

| Hello,

| 
|      Entirely re-jig the handling of default type-family instances
| (fixes Trac #9063)
| 
|      In looking at Trac #9063 I decided to re-design the default
|      instances for associated type synonyms.  Previously it was all
|      jolly complicated, to support generality that no one wanted, and
|      was arguably undesirable.
| 
|      Specifically
| 
|      * The default instance for an associated type can have only
|        type variables on the LHS.  (Not type patterns.)
| 
|      * There can be at most one default instances declaration for
|        each associated type.
| 
|      To achieve this I had to do a surprisingly large amount of
| refactoring
|      of HsSyn, specifically to parameterise HsDecls.TyFamEqn over the
| type
|      of the LHS patterns.
| 
|      That change in HsDecls has a (trivial) knock-on effect in Haddock,
| so
|      this commit does a submodule update too.
| 
|      The net result is good though.  The code is simpler; the language
|      specification is simpler.  Happy days.
| 
|      Trac #9263 and #9264 are thereby fixed as well.
| 
| 
| but I'm not expert so no offense! And if this is a mistake on my side,
| then I'm really sorry for false alarm.
| 
| Thanks!
