When you evaluate a lambda expression, the default args are evaluated, but the expression inside the lambda body is not. When you apply that evaluated lambda expression, the expression inside the lambda body is is evaluated and returned.
But that's not really the issue. I knew that the lambda was not evaluated but thought each generator expression got its own context rather than sharing one.
Taken in isolation, having one context per expression has more compelling semantics but it is inconsistent with the obvious transliteration of the generator into a loop.
