Just more data. Consider that a win.
Oh. That's very interesting.
I just tried gdb and I confirm that gdb understands well inlined
function. When I debug Python, gdb moves into Py_INCREF() or
Py_DECREF() when I use "next".
I also tried perf record/perf report: if I annotate a function
(assembler code of the function), perf shows me the C code of inlined
Py_INCREF and Py_DECREF!
