And this is exactly what I was wondering about - how a lambda function
needs to be treated differently. So is there a difference between:

class Foo:
    def __init__(self): ...


class Foo:
    def setup(self): ...
    __init__ = lambda self: self.setup()

? If so, what is the difference? Why are lambda functions not instrumented?
