Description
My framework relies on (smart) subclassing, but I've also got it to work with attrs mostly. Running into a problem like the following.
@attr.s
class BaseClass():
value = attr.ib(default=10)
@attr.s
class TestClass(BaseClass):
@value.default
def _not_value(self):
return 20

Research direction
Start by reproducing the reported example using attr.s, attr.ib, and the inherited value.default decorator. Trace how subclassed attributes and decorator methods are handled, then establish the intended behavior for TestClass before adding a regression test and confirming the example works.
