Overview

The Poll<void> specialization does not hold a value. It only indicates whether the operation is Ready or Pending.

Poll<void> provides value() accessors that resolve to ReadyType instead of void. This simplifies templates that use Poll, since all Poll instantiations offer a value() that returns an instantiable, referencable type.
