Either I'm not that smart, or in all my years as
a programmer, I've never
come across a linked list where part of it is in a loop, not all of it.
A "typical" application would be in a state machine, where the non-loop
bit at the head would be used for initialization.
OK, a pretty specific instance that almost nobody will actually encounter,
but I did once.
