makes me wonder if Racket is really up for non-toy numerics.
In contrast, SBCL uses tagless float arrays, so that array operations tend to be cache friendly. With adequate declarations, numerical code in SBCL tends to very fast (~1-3x C speed). I assume one can do the same with Bigloo and Chicken scheme as well.
