This expression:
(with-output-to-string
(where-is 'yank))
returns nil, and prints a message in the echo area. This one-line
change fixes it:

Tangentially, I wonder why where-is needs an optional INSERT argument
that means "don't print the result, instead insert it (oh, and use a
slightly different format)".

It's clearly meant for interactive use. I'm not sure if it answers your
question, tho.

For what it's worth, the code that gives what I was actually trting to
get from `what-is' is `(mapcar 'key-description (where-is-internal
foo))'. I don't know if there's a way to get that without using a
function with "internal" in the name.

Yes, this is not quite right: where-is-internal is not nearly as
internal as the name implies. It's just the natural function to use,
whereas where-is is the corresponding command.
Maybe we should fix the names to make where-is-internal less scary.
