At first this sounded like a good idea but 2 things pop to mind:
1. How does one get the pstat profiling output from the context manager?
Will printing out the results be the only option?
2. Usually when I profile I don't want to touch the code at all so
eventually if I'll use this context manager it'll be more akin to
with profile.Profiler():
main()
Which isn't much of a win over
profile.run('main()')
Now if you're talking about a reentrant profiler, that's interesting:
profiler = profile.Profiler()
while is_working:
with profiler:
do_hard_task()
do_a_hard_but_i_dont_care_now_task()
with profiler:
do_a_diff_hard_task()
and then I can call whatever method is there to get the pstat. If this is
the vision then it sounds awesome.
