I'm not sure it's that big a deal, but looking back over some of the
bits and pieces I wrote over the weekend there are a number of code
fragments that follow this kind of pattern:

def foo(x,y,...):
    acc=func1(x,y....)
    if some_test:
       acc = acc+func2(x,y...)
    else:
       acc = acc+func3(x,y...)
    return acc

Personally I'd  prefer to be able to write something like:

def foo(x,y,....):
   return func1(x,y,..) + 
          if some_test:
              func2(x,y...) 
          else:
              func3(x,y..)
