Update to python 3.7 #52
Conversation
Versions prior to 3.7 are EoL, and the lack of access to `from __future__ import annotations` in <=3.6 make it not worth working around. Pypi stats shows there is still some 3.6 utilization, but as breaking 2.7 support is typically handled by a major version bump, and going from 3.6 -> 3.7 is trivial, the regular maintaince of "a major bump happened" should be enough for them to push to 3.7.

Defaults to 16.04 (whatever dist that is) which doesn't have beyond 3.9

Used in places like @classmethod, where def foo(cls: Type[TJsonPointer]) -> TJsonPointer is dependent on the subclass. It's a small detail, but typing it correctly is really nice to people downstream.
In 3.11, PEP 673 makes this even easier, but since this was supporting every python version not EOL I didn't leverage it https://peps.python.org/pep-0673/

This may be overkill, but it made typing the Nothing object hints way easier to have a class it's an instance of. It could have been an empty class _Nothing: pass, but with ~5 lines more of code it gets the really nice property that every instance of _Nothing is the same instance.
Without that, checking default is _nothing would fail, as is checks id(lhs) == id(rhs) (aka "are they the same instance"? You can work around that by instead checking isinstance(x, _Nothing), but I prefer the syntax you had of is _nothing

Some type engines (e.g. pylance) get confused when you reuse names in place like this

was fun fighting Travis. Anyhow, sorry for the mangled work, I applied |

Thanks for the great work! If we drop <= 3.7 here, this will break stefankoegl/python-json-patch. Would you be up for looking into that as well? |

Yes, I am all for it! I'll link it when done.
