[Python-ideas] Decorator syntax restriction

Well, if the syntax was loosened to allow a subscript, i.e.

@a.b.c[x]( ...args... )

that would be something.  And allowing a dictionary ley as well - with the 
same syntax - would be even better; it seems hard to justify allowing one 
without the other.

On the other hand, maybe in future someone will come up with another 
'must-have' loosening of the syntax.  Eventually, don't you get to the point 
where it's simpler to allow anything?

Best wishes
