Personally, I don't worry about this: if I get the error message "too many parameters" or something, I compare the number of parameters in the called function with the calling function, and make the corrections.
But if you like, of course, you can accept a few parameters more, and then show your own error message if pcount() > x.
One way or the other, the other programmer must then look where he called your function, and do the corrections.
