Instead of a specific opcode, can't you use a suitable __reduce__ magic (or __getnewargs__, perhaps)? We want to limit the number of opcodes except for performance-critical types (and I don't think bound methods are performance-critical for the purpose of serialization). > I have created a patch at [1], which adds __func__ to some other > function types, as well as: > 1) adds AllFunctionTypes etc. to Lib/types.py > 2) inspect.isanyfunction(), inspect.isanyboundfunction(), > inspect.isanyunboundfunction() > 3) functools.unbind That sounds like a lot of changes if the goal is simply to make those types picklable.
