But that doesn't seem to be the case on Alphas.
Because I don't want to publish a huge list of numbers:
Total time for time_test2
IDL 5.4 with 5.4 version of factorial: 4.700
IDL 5.4 with 5.3 version of factorial: 4.698
IDL 5.3: 5.594
A nice little speedup for 5.4 regardless of the version of factorial used.
