Wow - I use <{cmd} a lot but I had never realised that >{cmd} works too.

What I do miss in rc (does any other shell do it?) is the ability to
open a read-write connection to a file.  For example you could test
webcookies(4) by doing something like:

<>[4]/mnt/webcookies/http { echo http://www.foo.baz >[1=4]; cat <[0=4] }

Because the webcookies protocol requires that you write the url and read back
the cookies on the same file descriptor, I can't see any way to do this in
the existing shell.
