I think you've summed it up nicely yourself in the above quote.
Argument 1: it makes it hard to avoid the forking when you don't want it.
Therefore, you should avoid the name "__iter__".
Argument 2: It seems cute.
Therefore, you should avoid the name "__iter__". "Cute" is a red flag
here warning you that it's a dangerously misleading choice of name.
So call it "snapshot()", or "copy()", but not "__iter__()".
