[melbourne-pug] Simple syntactic error?

Are you certain cb_calling is even being called?  If it's not, that'll  
be why your variable isn't carrying any value.

John's right, cb_calling should definitely declare state as global -  
and for style, I'd want the global declaration in keys() as well (not  
strictly necessary, but good form).

For debug, I'd drop either an "import pdb ; pdb.set_trace()" (and read  
up on how to use pdb, it's your friend ;) or a "print args" into the  
start of cb_calling, see exactly when it's called and what it's  
doing.  But if you're not getting any errors, then it's not a  
syntactic issue.
