bindings.el has this interesting section:

;;; These are dangerous in various situations,
;;; so let's not encourage anyone to use them.
;;;(define-key global-map [C-M-delete] 'backward-kill-sexp)
;;;(define-key global-map [C-M-backspace] 'backward-kill-sexp)
(define-key esc-map [C-delete] 'backward-kill-sexp)
(define-key esc-map [C-backspace] 'backward-kill-sexp)

So it looks like a feature that [M-foo] and ESC [foo] are separate.  All
other places where [M-foo] are bound explicitly bind ESC [foo] as well.

Andreas.
