I think that a time decorator will be a useful addition to the sandard library, as i find the current way of measuring execution time a bit tedious:

There are lots of ways to call timeit, but generally if you are calling it with number=1 then your results may not be trustworthy. (That depends on the function, of course.) There's a reason why timeit defaults to number=1000000 rather than 1.
@timef def fun_to_time(a, b): ...
The problem with that as an API is that once you have decorated the function to call timeit, how do you use it *without* calling timeit?
If you use functools.wraps, there will be a func_to_time.__wrapped__ but I don't think that calling that directly is a good interface.
I already made a basic implementation of it, and it's working well.
Can you explain what the timef decorator does? What arguments does it take, how do we use it?
