Ok, that's nearly perfect!
Only "nearly" because:
1. There are cases where you want the return value of the
"get_synset_link". 2. You sometimes need more than one callback, and you
cannot decorate two functions at once. For example, with Twisted you can
define a callback (called on success) and an errback (called on error).
But I agree that decorators help to solve a lot of problems.
Thanks for the answer
