Function Calls in Strings

• This works:

        @square = (0,1,4,9,16,25,36,49);
        print "3 squared is = $square[3]\n";

• So does this:

        print "3 squared is = $square[sqrt(4+2*6)-int(3/2)]\n";

• Arbitrary expressions are evaluated in double-quoted strings...

• ...when they are inside of array or hash subscripts
