I think we are talking about different things here. Call
M-: (eventp (read-key-sequence nil)) RET
and click with the mouse somewhere. You will get "nil" as a result
since read-key-sequence does not return an event, but rather an array
with the 0th element being an event.
key-binding in its current code by Chong can only deal with such an
event _sequence_ (which is not an event according to eventp).
If you thing it reasonable that key-binding should also react to
bona-fide events _not_ wrapped in an array, I can do this easily
enough in the change I am working on.

We have the situation that we want to look up an artificial
"follow-link" keymap entry depending on the keymaps where a click was
made. It would be nice to do this with
(key-binding click-event nil nil 'follow-link)

Replace it (actually, make a copy and replace the `down-mouse-1'
symbol in the copy with `follow-link').
