8 loop() ->
9 receive
10 % "receive" is a control structure that defines what "messages" we respond to
11 "casa" ->
12 io:format("house~n"),
13 loop(); % And each entry must make sure that we start the loop again
14 % If we had a "quit" message then it just wouldn't call loop()
15 % Because of the way that tail recursion works then calling this last
16 % has almost no overhead, but doing it in the middle would.
