One very minor comment now I've tried this:

% sysread -i fd
sysread: integer expected: fd

I think it would probably be appropriate and consistent with other
similar contexts for this to do matn eval, even though the workaround is
obvious and trivial.  C.f. "sysopen -u fd" (though of course there's no
choice in that case) and

% print $(( systell(fd) ))
8192

However, we're not actually missing anything by not.
