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>
