Sarcasm was not intended - I'm simply not a native english speaker and I don't
mention it in every post :-)
What I wanted to say - without offending you - was: You asked a lot of
questions, therefore have a lot of experience with this list, and should know
that and how the questions influnce the answers. As more precise the
question, as more precise the answer can be (mostly not from me ;-) ).
["precise" is hardly the correct english word, but...]

I don't know of such a thing. How should such a feature "don't allow too many
arguments without coding something that specifies 'many'" be implemented?
Christian mentioned prototypes, maybe that's what you're looking for, but they
should be avoided, they do more than just defined the maximum of possible
arguments, and involve some sort of "coding".

I never heard of a way to pass arguments to (normal) scalars in perl. Somebody
else may know more.

I don't think there is such a rule, but wait for other answers.
