i generally make a block the winner because it's bigger visually and harder to
type - ergo one generally meant it if one typed it.  whereas a hash is easy to
accidentally pass using

   attribute(*args){ Time::now }
                ^
                ^
                hash in here

suppose you could throw an error too - not my style - but it makes sense.

cheers.
