A lot of wrong typing hints?

[larsblumberg]

Describe the bug
Using a LSP server with a Reflex app gives a lot of typing errors although all code is correct.

To Reproduce
Enable a LSP such as pylsp-mypy in a Reflex project.

• Code/Link to Repo: n/a

Expected behavior
LSP does not show typing errors when Relfex is used correctly.

Screenshots

Specifics (please complete the following information):

• Python Version: 3.11
• Reflex Version: 0.7.3
• OS: Pop_OS

Additional context

Using these LSP dependencies:

[tool.poetry.group.dev.dependencies]
pylsp-mypy = ">=0.7.0"
python-lsp-ruff = ">=2.2.2"
python-lsp-server = ">=1.12.2"

The recent reflex updates broke ObjectVar typing again, for the 3rd time :/

You can mitigate it by annotating your vars with ObjectVar or use your_var.to(ObjectVar).

we had __getattr__ defined in Var, which made typing think "oh yea i could do this", but all it did was raise errors, so we thought it would be best to move it into a non-typing context
as an incident for this, Vars that would get downcasted to ObjectVar now would make a "false" alarm on how they don't have __getattr__
while we would like for Var (or something similar to it, maybe AutoVar) downcast to ObjectVar automatically, this is a restriction in the python typing system that wasn't resolved, so we don't have options other than to either type things as ObjectVar or require an additional function call, like .guess_type()

the relevant ticket for this is python/typing#1273 once again
