From stackoverflow:
http://stackoverflow.com/questions/7549628/whats-wrong-with-the-following-unbind-script/7549825#7549825
User tries:
(dolist (abcc '("C-a" "C-b"))
(global-unset-key (kbd abcc)))
Which fails.
(defmacro kbd (keys)
"Convert KEYS to the internal Emacs key representation.
KEYS should be a string constant in the format used for
saving keyboard macros (see `edmacro-mode')."
(read-kbd-macro keys))
kbd should evaluate its parameter before calling the read-kbd-macro
function. Its parameter types should all be self evaluating.

Really sorry for the noise. Upon closer inspection, I realize that
`kbd' is meant to be used on constants, so that byte-compiled code is
more efficient. Please close this bug.

No, it should not. Read the replies to that stackoverflow question (use
`read-kbd-macro').

Yes, kbd should have been defined as an alias of read-kbd-macro
(i.e. a function) and mark it as pure so the byte-optimizer can
precompute it when applicable.
I know that changing a function into a macro introduces many
compatibility problems, but maybe changing this macro into a function
can be done without problems?

How do you mean by 'mark it as pure' and how to do it?

Sounds good.

(put 'kbd 'byte-optimizer 'byte-optimize-pure-func)

That's been done.
