find -name when name contains a slash

[Avis, Ed]

% find . -name foo/bar

Actual output: nothing
Desired output: warning: don't be silly, Unix filenames can't contain
a slash.

Alternatively, it could list all files called foo which are inside a
directory called bar under the current directory (which is what I was
kind of hoping for).
