  24     ECMA Section:       Function.length
  25     Description:
  26
  27     The value of the length property is usually an integer that indicates the
  28     "typical" number of arguments expected by the function.  However, the
  29     language permits the function to be invoked with some other number of
  30     arguments. The behavior of a function when invoked on a number of arguments
  31     other than the number specified by its length property depends on the function.
  32
  33     This checks the pre-ecma behavior Function.length.
