Hi!
I want to throw `logging.exception()` [1] but using the traceback of
caller's function, so:
---------
up=1
frame = traceback.extract_stack(limit=up+2)
---------
Reading the code, `traceback.print_exception` prints the message from
a record got with `LogRecord.getMessage()` [2] So I'm supposed that
I'd have to use it to get a new record that can be used by
`traceback.print_exception`.
