I guess I don't understand why. Why would
you save a profile if you don't want to
later access it?
OK, you might want to compare two profiles,
with `=', but I'd think that would be less
common than looking again at a profile that
you saved.
If you delete a profiler report buffer then
you have to profile all over again, to
revisit it. Comparing has a key (`='), but
just revisiting doesn't. Why?
I haven't been using profiler, so I don't
really understand its use, I guess. What
am I missing? Why is saving a frequent
operation but using (revisiting) a saved
profile is rare?
