use `operator` on a class method fails about aiostream HOT 3 CLOSED

Hi @jenda1 <https://github.com/jenda1>, thank you for creating this issue. The problem here is that the decorated generator becomes a Stream subclass, in order to provide support for pipe-lining (|), slicing ([]) and concatenation (+). That means testit is *not* a method and this is why you have to pass the t instance explicitly in your workaround. Instead, you could consider this alternative: @operatorasync def stream_from_test_instance(test): yield test.n class test: n = 123 def testit(self): return stream_from_test_instance(self) Or, since streams are reusable: class test: def __init__(self, n): self.n = n self.stream = stream_from_test_instance(self) def testit(self): return self.stream The error message you got isn't really explaining what's happening though. I think I'll try to detect self or cls arguments and raise an exception with a proper explanation. Hope that helps, thanks again. — You are receiving this because you were mentioned.
