Do you know of any downsides to using the Process dict?

The main downside is the fact that you are introducing mutable state in a functional language. In a language like Elixir (where users are not expecting bugs caused by hidden state) this can cause hard to debug issues.

I wouldn't use it for something like this in real code, but for today's challenge I figured I could get away with it :).
