Hello,
I've been working on some unsafe fast I/O procedures for my own use,
and I thought I'd make them an extension, if more people would
like to use them.
The "fast-io" extension would have these procedures:
Implemented and tested:
- write-fixnum, read-fixnum
- write-flonum, read-flonum
- writ

Does this refer to a textual or a binary format file?

Textual. I had no intention of using binary files, although
that could be nice t

For those I have been making good use of the endian-port egg (not
released for chicken 4 yet though); I wonder how the benchmarks would
turn out, but th

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

How about specialized-io or optimized-io? The io routines aren't
general-purpose like the basic Chicken ones,

Oh right, so it's ascii then... not like endian-port at all.

BTW, I've benchmarked complex reading ad writing too. I suppose
the difference is huge for reading complexes because the read
