  * Re-introduce pattern queries in hat-observe.  There is now a proper
  lexer and (combinator) parser for patterns, and it can deal with
  infix constructors/variables using the normal Haskell syntax.  The
  only caveat with infix patterns is that fixity is not known, so the
  user must parenthesise them explicitly.
