Others have answered your programming question, but I'd like to comment 
on your original premise.

I assume you only want this special behavior when the command is bound 
to C-w, because the "w" means "word" to you (was this the kill-word 
command in some other editor you've used in the past?).  But if you use 
defadvice, your advice will be obeyed even if the command were on some 
other key.  Or if a function used (call-interactively 'kill-region).

So I think it would be better to write a new function, and bind C-w to 
that.
