  21 [h1 Description]
  22
  23 Template class representing the error that the closing element of an
  24 "['opening element] ... ['closing element]" structure is missing. (eg. a closing
  25 paren is missing). `Line` and `Col` point to the beginning of the
  26 ['opening element] (eg. the opening paren). `Msg` is the error message the
  27 parser trying to parse the ['closing element] failed with.
  28
  29 It supports currying: `unpaired<Line, Col>` is a
  30 [link metafunction_class template metafunction class] taking one argument: the
  31 `Msg` element and returning the corresponding `unpaired` value.
