Subject: correct for asyncio.Runner not in py311 stubs
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=63add624878c9a7a27d6d230cbcf3ccf3786ada1;p=thirdparty%2Fsqlalchemy%2Fsqlalchemy.git

correct for asyncio.Runner not in py311 stubs

Second attempt.  TYPE_CHECKING has to be unconditional because
mypy doesnt know anything about py311 / py312 booleans
