Sentinels in collections, was RE: Primitive Queue<any T> considerations

Hi,

Agreed, so maybe I misinterpreted Richard’s email (I tried to mitigate by

Well I was originally thinking in terms of the Queue interface itself,
which needed a sentinel taken out of the user's domain. I don't think its a
problem to expand the discussion though and you're certainly right to
observe that there are two different kinds of sentinel.
