Hello Felix,

I've been thinking about this for a while, and
I'm having a hard time picturing what you are
attempting to do.  When I think of vector math
I think of things like "add 1000 elements of
array1 to 1000 elements of array2".  Such
operations should not require any procedure
overhead beyond the initial procedure call.

Also, with respect to fast array access for
dimensions higher than 1, have you looked
at the MultiArray package?
