  Hello Sam.

  I am using racket from the console, not using DrRacket.   I just copy the code
with control-c and paste with control-v then wait a seconds for the definitions
to be loaded in memory and then run the test.

 I was going to use raco exce ... but it asks about a module (perhaps I should
read the section about using raco to generate a standalone executable).

 Anyway, my point was that I was expecting something more from typed racket.
Since typed racket use types (like declaring type in sbcl) I was expected better
perfomance, that's all.
