Hi JP
Not quite:
def f(): ... yield None ... f(1, 2, 3) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: f() takes no arguments (3 given)
Ah... thanks.
And unfortunately, there is essentially no way to differentiate this case from a case where the call to `f´ succeeded but some code executed as a result of that raised a `TypeError´.
Right, not without looking at the text of the exception, which, apart from being extremely would be unreliable. Too bad there's not a Python exception for incorrect function/method arg passing.

Ha! There's pretty much the whole of this thread in there. I'll look more carefully in trac next time. I did look at some point, and saw another issue discussing what to do if a non-deferred is yielded. Thanks again. Terry
