Don't knock `ignore'.  It's an incredibly useful and versatile command.
I've got it bound to C-c C-g, C-x C-g, C-x 4 C-g, etc., so I can cancel
with C-g "in the middle of a key sequence".

It's also useful for dumping out variable values; in the middle of a
defun, you can insert

    (ignore foo bar baz)

, and then do M-x trace-function-background <CR> ignore <CR>.  This is a
useful trick for places edebug can't reach.
