Dealing with cyclic dependencies

[StephenCarboni]

We need a way to deal with cyclic dependencies. My suggestion is to provide a convenient way to import modules late.

def do_import():
    from machine import MachineState # machine module may import this one

class MachineReport(BaseModel):
    class Config:
        late_import = do_import

    state: 'MachineState'

I had to do this yesterday, is documented. Take a look at:

It seems this only works for models defined within the same module, but not from another package. What you're describing isn't a cyclic import, but a forward reference to a model which is implemented later in the same code.

This seems to continue the discussion from #1873, right?
