consider returning a unique_ptr with a custom deleter from peek()

[badair]

Have you considered this already? This way, unpeek() would be automatic.

we have considered. the only issue is if I want to hold a reference to the head for multiple returns. Although, I suppose we could do a peek_s or something that would implement this. It could return an object then unpeek in the destructor.......will be a bit complicated for the data forwarding where the same pointer is passed from the input port to the output port but it could be managed.....will see if I can add this after I merge the development DSL parser.
