Raymond Hettinger added the comment: When we added LIST_APPEND (the first of the custom opcodes intended for optimization), it was done only because it was frequently used in inner loops where it provided real benefits to users.
In contrast this opcode seems like a waste. Historically for opcodes, we've valued orthogonality and parsimony. The opcode set was intentionally kept simple and minimal. The recent opcode additions have disregarded these values. ---------- nosy: +tim.peters _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28800> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
