Matthew,
Thanks very much for the comments. I'll get to work preparing an updated
version using #:size soon, and send it to Sam for pushing. As for the issue of
a #:size that doesn't match the length of the iteration, I have been thinking
about adding a check inside the loop (for sizes that

Hello all,
The attached patch against the current git master adds an flvector-copy

Hello Racket Developers,
I thought I would write a quick note about building Racket on Mac OS X 10.6.8
with the new clang compiler (the new front-end to the LLVM compiler backend
