     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.
