     1 #!/usr/bin/env python     2      3 """     4 Native library functions for lists.     5      6 None of these are actually defined here. Instead, native implementations are     7 substituted when each program is built. It is, however, important to declare     8 non-core exceptions used by the native functions because they need to be     9 identified as being needed by the program.    10     11 Copyright (C) 2011, 2015, 2016, 2017 Paul Boddie <>    12     13 This program is free software; you can redistribute it and/or modify it under    14 the terms of the GNU General Public License as published by the Free Software    15 Foundation; either version 3 of the License, or (at your option) any later    16 version.    17     18 This program is distributed in the hope that it will be useful, but WITHOUT    19 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS    20 FOR A PARTICULAR PURPOSE.
