Fw: the syntax of PSL prev function

One of our customers suggested the following new syntax for the prev
built-in function
      prev[Number](Any_Type)
that will replace the current syntax
      prev(Any_Type [ , Number]).

I think that it makes sense because numbers and ranges are usually enclosed
in square brackets and the number parameter of prev is the only exception.
Moreover, the prev function and the next operator are quite the same in the
eyes of the user. The new syntax suggests similar syntax for both.
