The main problem with this is that the following code does not make any
sense:
"%(a)%" % dict(a=3)

It has no semantic meaning (take the dictionary paramater a, and do nothing
with it).
It must be a user bug (except in very wierd cases).

I agree that when I consider the implementaion, it makes sense, but as a
python user, this behavior is really non-intuitive.
