Antoine Pitrou <pit...@free.fr> added the comment: I understand this is indeed unintuitive. The reason list objects support the C "mapping protocol" in 3.x is that it is how slicing of lists (and tuples, for that matter) is implemented. Perhaps the documentation should carry a warning about this.
Unfortunately, right now there is no easy way in C to check that an object implements a given ABC. ---------- assignee: -> georg.brandl components: +Documentation, Interpreter Core -Library (Lib) nosy: +georg.brandl, pitrou priority: critical -> high _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5945> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
