+Note that the parentheses around this tuple are required, because
+``except ValueError, e:`` was the syntax used for what is normally

+This means ``except RuntimeError, TypeError`` is not equivalent to
+``except (RuntimeError, TypeError):`` but to ``except RuntimeError as
+TypeError:`` which is not what you want.

 The last except clause may omit the exception name(s), to serve as a wildcard.
 Use this with extreme caution, since it is easy to mask a real programming error
 in this way!  It can also be used to print an error message and then re-raise
