My only problem with this syntax is that I expect the common cases 
(mine, anyway) to be zero or one decorators per function, so the extra 
block and indent seems a bit excessive compared to the current 
@prefix-symbol-decorator proposal(s).  It is, of course, far better 
than typing the function name three times though! :)
