Yep, any implemented system that has nodes must have some way to identify
them internally (whether they are termed anonymous or not).  Point is that
the anonymous ones just can't be accessed by name from outside that system.
The only way to address an anonymous node from outside the implemented
system is by criteria ... for example I'm talking about the nodes in your
system for which [foo bloop; bar goop] and of those nodes I wish to say [gar
poop] ... oh ... and I will be expecting that you have only one such node.

Well maybe that is what some people use them for.   The primary reason,
imho, is that we got so many nodes we can't name them all ....  tis
impossible .... twill always be impossible.   But that doesn't mean that we
can't start talking about things which are impossible to name or for which
(in a distributed system) it is infeasible to name.   So next time you go to
the beech select the first grain of sand that is touched by your left pinkie
and send it to me ...

.... along with a dollar bill of course.
