Update of /cvsroot/python/python/dist/src/Modules In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv9217/Modules
Modified Files: collectionsmodule.c Log Message: Make sure "del d[n]" is properly supported. Was necessary because the same method that implements setitem also implements delitem. Also, there were several good use cases (removing items from a queue and implementing Forth style stack ops).
