The constants in this module are used in Haskell and are also
converted to Python.

Do not write any definitions in this file other than constants.  Do
not even write helper functions.  The definitions in this module are
automatically stripped to build the Makefile.am target
'ListConstants.hs'.  If there are helper functions in this module,
they will also be dragged and it will cause compilation to fail.
Therefore, all helper functions should go to a separate module and
imported.
