Just a few quick questions regarding the places code:

1. Is `?` like `if`? For me it says that it is an undefined identifier.
2. If I understand correctly, the place is looping and in each iteration is 
looks if there is a message on the channel, which matches something. Is this 
creating a lot of extra work for looking on the channel all the time?
3. What are `p`, `_i`, `_o` and `_e` doing?
4. Could I replace `set!-values` with a `let`?
