If I understand you correctly, you seem to be trying to apply "isimplemented" to the problem of predicting which specific inputs to a parameter would be valid. I don't think that problem is tractable--it's way too context-specific. Exactly! It's too context sensitive to belong on a generic signature object. Without isimplemented, all the properties of the signature object should only change if you alter the parameter list. How a parameter is dealt with in the function should not affect the signature of a function.
I agree. It seems to me is_implemented solves too small a class of the problem it attacks to be worth including in the signature.
