Hi Robby,

Can you give a spec for the behavior of Listable attribute? In other
words, how can I write a function

ListableBehavior[f_,args___]

such that the result returned is equivalent to executing f[args] where f
has the Listable attribute? (Of course, without using the build-in
Listable functionality.)

I dabbled with Thread, but don't have the exact solution.
