---------------------------------+------------------------------------------
 Any literate script where the hash symbol # is in the first column of a
 file does not compile in ghc.

 For example,
 {{{
 > foo = 1 + 2

 #
 }}}
 will give rise to the following error:
 {{{
 lexical error at character '\n'
 }}}

 This is rather annoying, since # is used in markup languages as a heading
 delimiter. The example compiles fine using hugs.
