I forgot -- whatch out for the file size and time to be spent in
benchmarks! You may want to change the value of +max+ in
benchmarks/run.scm to a smaller value and increase it gradually.
BTW, I've benchmarked complex reading ad writing too. I suppose
the difference is huge for reading complexes because the read
procedure doesn't know that it's a complex number.
One caveat: fast-io reads and writes exactly as printf/scanf do,
so the external representation may not be the one used by your
other Scheme programs!
