The dot operator can be used as a shorthand for accessing a sub item:
-- ``expr.member`` is roughly equivalent to ``expr % "{member}"`` if ``expr``
+- ``expr.member`` is roughly equivalent to ``expr % '{member}'`` if ``expr``
returns a non-list/dict. The returned value is not stringified.
-- ``dict.key`` is identical to ``get(dict, "key")``.
+- ``dict.key`` is identical to ``get(dict, 'key')``.
