Let me make sure I understand.  You want to be able to write this:
I understand the consistency argument.  Since most uses of read will be
in a "read until EOF loop," however, you would require that other changes
be made to rc.  I think this is enough to kill your idea.

Anyhow, let's take a look at your idea.  That is,
should set $status to the exit value of foobar.  What should
set $status to?  Leave it unchanged?  What about
if the directory is empty?  And if it isn't? What about
when /foo doesn't exist?

You are making a simple shell very complicated, don't you think?
