the call fails as none of the clauses matches. should be the call fails as none of the clauses match.

Note from the Author or Editor:
The current text isn't incorrect, as "matches" corresponds to "none", i.e., "none matches", and "none" isn't necessarily plural. However, many readers are more comfortable considering "none" as plural, so we will change this text to be clearer.

Second Paragraph

In the sentence Any other events coming out of sequence (such as Sunset when in state Day) are handled only after a transition to a state where they can be dealt with. the phrase in parentheses should be either "(such as Sunrise when in state Day)" OR "such as Sunset when in state Night)"

Note from the Author or Editor:
Already fixed in copyedit. Changed "In state Night, event Sunset causes" to "In state Night, event Sunrise causes" and also changed "(such as Sunset when in state Day)" to "(such as Sunrise when in state Day)".

Bottom code listing

stop() calls gen_fsm:sync_send_all_state_event, but we implement handle_event (not handle_sync_event). Maybe stop() should call gen_fsm:send_all_state_event instead?

Note from the Author or Editor:
This is already fixed in copyedit. The fix is, near the bottom of page 137, to change "the event is handled in handle_event/3" to "the event is handled in handle_sync_event/4" and change "handle_event(stop, _State, LoopData)" to "handle_sync_event(stop, _From, _State, LoopData)".
