 If an identifier is out-of-scope but inside a static form ({{{static f}}})
 then GHC says expression not closed, when really it should just say
 identifier out of scope.

 {{{
 t.hs:6:5: error:
     Only identifiers of top-level bindings can appear in the body of the
 static form:
       static f
     but the following identifiers were found instead:
       f
 }}}

 We just want:
 {{{
 t.hs:6:12: error: Not in scope: ‘f’
 }}}
