Hi all, Today I found out why on the py3.6 branch dis does not work properly. It's because cpython 3.6 switched to a slightly different bytecode format, where every instruction is 16 bit long, see these issues: https://bugs.python.org/issue26647 https://bugs.python.org/issue28050 Do we want to implement that too, so that we stay closer to what CPython is doing? Or should I partially undo the 3.6 changes to dis.py to fix it? Also, does anybody have a high-level overview which big things are missing on the py3.6 branch? Or what the current blockers are? Cheers, Carl Friedrich
