After learning about TYPE_CHECKING i made it a habit to put all imports that were only needed for type checking into an if TYPE_CHECKING: guard. But now I am wondering if that is actually intended to be used like that. Checking whether an import is only needed at type checking time can get quite tedious and sometimes you run into situations were you introduced some code that made the import a requirement at runtime.
How do you use TYPE_CHECKING? Whenever it is possible or only when using it actually solves a circular import?
I don’t like having to quote the types, so I use it exclusively for avoiding circular imports.
