Written as executable scripts. Tested with Scala-2.11.2

Though it is not measuring the raw performance because the JIT takes time. If I execute one 100000 iterations loop before the measurement (in order to force the JIT) then 100000 iterations is too short to reliably conclude about the performance (less than 10ms)

I am not sure that it does not use some kind of memoization.

It does not memoize unless explicitly asked.
