    REPLACE

    If the replication operator is used on a function
    call operand, the function need not be evaluated
    multiple times. For example:

       result = {4{func(w)}

    may be computed as

       result = { func(w), func(w), func(w), func(w)}

    or

       y = func(w) ;
       result = { y, y, y, y}

    This is another form of expression evaluation
    short-circuiting.

    WITH

    When a replication expression is evaluated, the
    operand shall be evaluated exactly once, even if
    the replication constant is zero.
