I just get a message that the code block produced no output and that 'np' is not defined.  Just to check, when I put the import statements directly within my code block it works fine.

I don't really want a stateful session (nor does ob-racket support sessions) so I essentially want the equivalent of automatically including it everywhere so I don't have to type it out all the time (and have it screw up syntax coloring/indentation).
