sys.call_tracing

 From the documentation on the sys module at https://docs.python.org/3/library/sys.html:
sys.call_tracing(/func/, /args/)
Call |func(*args)|, while tracing is enabled. The tracing state is saved, and restored afterwards. This is intended to be called from a debugger from a checkpoint, to recursively debug or profile some other code.
Tracing is suspended while calling a tracing function set by |settrace()| <https://docs.python.org/3/library/sys.html#sys.settrace> or |setprofile()| <https://docs.python.org/3/library/sys.html#sys.setprofile> to avoid infinite recursion. |call_tracing()| enables explicit recursion of the tracing function.
Is there any reason it doesn't support
sys.call_tracing(/func/, /args/, kargs)
to call
func(*args, **kargs)
?
