Indeed.

Okay, thanks. I asked because I thought you were only planning support
the former case.

It's not quite clear to me how this is consistent with how Eshell
currently works. When you type "echo hi | cat" is it right to say that
"cat" is evaluated to produce the thing to which the output of the first
command is piped? Perhaps I'm not thinking broadly enough.
