Getting the whole agent state is often a bad idea, so we want to force you
to think if you really need the whole state or part of it. Depending on the
data, you can have a drastic difference between:
Agent.get(pid).some_field
and:
Agent.get(pid, & &1.some_field)
So in the cases you do want it all, being explicit about it doesn't hurt.
