I'd say they might both have *type* number, but I wouldn't use the same
identifier 'number' for both of them.

Generally speaking, I'd suggest that each argument to a function be uniquely
named, even if only number_1, number_2, ..., number_i.

If two or more arguments to a given function are given precisely the same name,
I might get the impression that they had to be the same value. I can't think of
a single programming language in which I can refer to the first or nth argument
to a function using interchangeable identifiers. 

Example of ambiguity:

SUM(number, number) {
  return number + number;  // ???
}

+1, I'd appreciate their input as well :-)
