-- | Alternative to 'show' to display a 'ParseException' on the screen.
--   Instead of displaying the data constructors applied to their arguments,
--   a more textual output is returned. For example, instead of printing:
--
-- > InvalidYaml (Just (YamlParseException {yamlProblem = "did not find expected ',' or '}'", yamlContext = "while parsing a flow mapping", yamlProblemMark = YamlMark {yamlIndex = 42, yamlLine = 2, yamlColumn = 12}})))
--
--   It looks more pleasant to print:
--
-- > YAML parse exception at line 2, column 12,
-- > while parsing a flow mapping:
-- > did not find expected ',' or '}'
