Leaving out the argument with uppercased P, it sends nil --correct--
whose numeric value is considered 1 again.

Understand it might be considered a feature, but think the caused
inconsistency weights in more.
So you also disagree with nil meaning "the default value", do you?
Because, according to you, nil cannot possibly stand for any value but
zero,

At least if something supposed the a "numeric argument". Sure, that might be translated. But than that default should be mentioned when the form is introduced.


  without risking to be "inconsistent", is that right?

But if you do accept that nil can stand for the default value, why
cannot you accept that in the case of repeat count it stands for 1,
i.e. that 1 is the default value in this context?


I can accept that and live with it. Just thought current state is not the best we can have.
