Yeah, that would be nice. I see you already have open-read-file* and
open-write-file*, but it would be nice just to have (open-file* "file"
"r") or (open-file* "file" "w+"), (or whatever system you use to represent
the modes of the file: :append and the like I think) etc.

Also, don't forget to do the rest of the FILE* operations like fseek,
ftell,freopen,fwrite,fread, etc. Some of them might be able to be
overloaded with current functions that do this for file descriptors.

I think the real difference between the open() and fopen() call semantics
is that fwrite() and fread() will return more of what you expect(fuller
reads/writes of your data) instead of partial reads and writes the
read() and write() will perform for you.

Thank you very much!

Thanks! It just seems sad to forget the lessons of unix in this particular
area.

Thank you.
