* Some kind of strong typing: SEQUENCEs require the exact **type** of
settable values, even when they are inherited (assigning ``Integer``
to the field with the type ``CMSVersion(Integer)`` is not allowed)
automatically set required tags)
* Descriptive errors, like ``pyderasn.DecodeError: UTCTime
(tbsCertificate:validity:notAfter:utcTime) (at 328) invalid UTCTime format``
-* ``__slots__`` friendliness
-* :ref:`Pretty printer <pprinting>` and

- conveniently replace utilities like either ``dumpasn1`` or
- ``openssl asn1parse``
-* Could be significantly faster and have lower memory usage.
