While we're on profile convenience features, how about adding two context managers:

- one that just profiles a block and prints the profile (or dumps the data to a file)

- one that takes a Profile instance and enables profiling to that instance

E.g. (1)

with cProfile.runblock([file]):
    <your code here>

or (2)

p = cProfile.Profile()
with p:
    <your code here>

Also a decorator corresponding to (1):

@cProfile.runfunc([filename])
def myfunc(args):
    <stuff>
