New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
DeprecationWarning at compile time is output multiple times to the stderr (on
console from which IDLE was ran), but not to IDLE Shell window.
For example, when enter '\e':
$ ./python -m idlelib
Warning (from warnings module):
File "<pyshell#0>", line 1
'\e'
DeprecationWarning: invalid escape sequence \e
>>>
Warning (from warnings module):
File "<pyshell#0>", line 1
'\e'
DeprecationWarning: invalid escape sequence \e
>>>
Warning (from warnings module):
File "<pyshell#0>", line 1
'\e'
DeprecationWarning: invalid escape sequence \e
And when close IDLE, additional output is printed in 3.8+:
>>> Exception ignored in: <idlelib.run.PseudoInputFile object at 0x7f9e3b4a15a0>
