[issue40199] Invalid escape sequence DeprecationWarnings don't trigger by default

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

On Win 10, with recently compiled 3.7.7+ and 3.9.0a5+, I get 4 warnings also.

>>> import warnings
>>> compile("'\d'", "<string>", "eval")
<stdin>:1: DeprecationWarning: invalid escape sequence \d
<string>:1: DeprecationWarning: invalid escape sequence \d
<code object <module> at 0x00A65DC0, file "<string>", line 1>
>>> warnings.resetwarnings()
>>> compile("'\d'", "<string>", "eval")
<stdin>:1: DeprecationWarning: invalid escape sequence \d
<string>:1: DeprecationWarning: invalid escape sequence \d
<code object <module> at 0x00A66190, file "<string>", line 1>

Numerior, what 3.8 binaries are you running?  I suspect that this should be closed as 'out of date'.
