A state machine implementation is often done as a "switch" statement (read "if ... elsif ..." in Perl) and can get pretty long even when most of the work for each state is factored out into individual subs. There are ways to avoid the "switch" (dispatch tables for example), but often the operation of the state machine becomes less obvious.
