Alternative decorator syntax decision

hi,

I vote:

J2, J2, J2

and thus the split-vote mechanism is completely defeated.  I don't
think you can enforce 2nd-choice voting on a newsgroup.  I find suite
expansion to be far more pythonic than anything else we've come up
with.

Just to be clear, the following is J2:

while this is E4, which I think has some traits that Guido has already
vetoed in http://mail.python.org/pipermail/python-dev/2004-August/047279.html:

I like "decorate" much better than "transform", because "transform"
encompasses more than the specific concept of decoration.  If there is
a concern that decoration is a larger concept than what is proposed in
PEP 318, then I would consider some other, more specific verb.

Verb it must be, though, as opposed to something adverbial or
prepositional or even gerundy.  It seems to have been made quite clear
that decoration is a separate action from definition.  If we use a
word that isn't another transitive verb, that word will attach itself
to "def" and the syntax will obscur the semantics.

Solutions that are already or obviously will be rejected by Guido
contribute to noise levels.  b-)
