Typing this out though does make me think of an interesting idea. If there was something like __getself__ in addition to __setself__, you could implement things like MyInt. __getself__ would look something like:

class MyInt: def __init__(self, value): self.value = value def __getself__(self): return self.value def __setself__(self, value): raise ValueError("Cant set MyInt") x = MyInt(2) print(x) -> 2 type(x) -> MyInt

Now I have not really thought through how this would work, if it could work...

How does print know to call getself, but type know not to? ChrisA
