Comment (by uwe):

 I've prepared a tar archive with all sources needed
 to reproduce the error.
 The URL is
 http://www.fh-wedel.de/~si/HXmlToolbox/hxt-ghc10-error.tar.gz

 Please untar the archive, cd into hxt-ghc10 and
 run "make error".
 This will cd into examples/arrows/hparser,
 compile the test prog with -O0 and execute a
 simple test run.

 Then the build is repeated but with -O and
 the test prog issues <>.

 There are a lot of sources, that shouldn't have
 any influence on this error. Interesting modules
 could be the Control.Arrow.* modules.

 Probably worth merging, if it goes over cleanly

 OK I have mostly-implemented this feature request
 {{{
 Tue Oct 28 11:54:27 GMT Standard Time 2008  [EMAIL PROTECTED]
   * Mostly-fix Trac #2595: updates for existentials

   Ganesh wanted to update records that involve existentials.  That
   seems reasonable to me, and this patch covers existentials, GADTs,
   and data type families.

   The restriction is that
 The types of the updated fields may mention only the
 universally-quantified type variables of the data constructor

   This doesn't allow everything in #2595 (it allows 'g' but not 'f' in
   the ticket), but it gets a lot closer.
 }}}
 No need to merge.

 I've integrated this with GHC 6.8.3 sources. There's not much to it.

 With quotes, it uses string escapes and retains spaces:

 {{{
 Prelude> :set prompt "{-  %s\n -} "
 {-  Prelude
  -}
 }}}

 Without quotes, it uses only character escapes:

 {{{
 Prelude> :set prompt {-\SP\SP%s\n\SP-}\SP
 {-  Prelude
  -}
 }}}
