Hi Kristjan The strong reference there is a feature. Descriptors keep the class alive if somehow the class disappears and the descriptor itself does not. Please don't change language semantics (yes, this is a change in semantics), just because the test suite passes - I can assure you there are people doing convoluted stuff that expect this to work.
