Nested Scopes ... next tail recursion?

[Richard Davies]

> def tailrecursedef(f):

additionally defining

def tailrecurse(*a, **b): 
   return {'tailrecurse': (a,b)}

allows us to tidy up:

> def bit(i):
>    if i==0:
>       return "bottom"
>    else:
>       return {'tailrecurse': ((i-1,),{})}

to:

def bit(i):
   if i==0:
      return "bottom"
   else:
      return tailrecurse(i-1)
