I tried doing a bash equivalent to this, involving opening a remote
connection and holding it open while feeding it numbers one at a time. But
I couldn’t get that to work. Something about the syntax for dynamic
redirections (and closing of dynamically-assigned FDs) that I don’t
understand. Or that isn’t implemented properly.

But this does work:

    ldo@theon:~> echo 123 + 456 | ssh hypatia bc
