> PyStructSequence_InitType2() is not compatible with subinterpreters: it uses static types. Moreover, it allocates tp_members memory which is not released when the type is destroyed. But I'm not sure that the type is ever destroyed, since this API is designed for static types.

IMO, I suggest to create a new function, PyStructSequence_FromModuleAndDesc(module, desc, flags) to create a heaptype and don't aloocates memory block for tp_members,something like 'PyType_FromModuleAndSpec()`.

I don't know there have any block issue to do this converting operation. But I can take a look.

@petr ping, Petr, do you have any better idea about this question :)
