timing

timing e -- evaluates e and returns a list of type Time of the form {t,v} , where t is the number of seconds of cpu timing used, and v is the value of the the expression.

The default method for printing such timing results is to display the timing separately in a comment below the computed value.

     i1 = timing 3^30
     
     o1 = 205891132094649
          -- 0. seconds
     
     o1 : Time

     i2 = peek oo
     
     Time{0.,205891132094649}
