(I'm working on PEP 318...)
Is there a concensus on the order of application for decorators? Should def func(a,b) [d1,d2]: pass be equivalent to def func(a,b): pass func = d1(d2(func)) or def func(a,b): pass func = d2(d1(func)) or is it a coin toss? I'm having trouble finding coherent discussion on this topic in the archives. Pointers appreciated.
I think the consensus was d2(d1(func)). I.e. application from left to right -- just like all lists are evaluated L2R in Python.
