The mechanism is to always add a hashable element, or if it is not
hashable, the element is checked to see if it has an
! \method{_as_immutable()} method which returns an immutable equivalent.
! Since \class{Set} objects have a \method{_as_immutable()} method
returning an instance of \class{ImmutableSet}, it is possible to
construct sets of sets.

\method{remove()} methods which need to hash an element to check
for membership in a set. Those methods check an element for hashability
! and, if not, check for a \method{_as_temporarily_immutable()} method
which returns the element wrapped by a class that provides temporary
methods for \method{__hash__()}, \method{__eq__()}, and \method{__ne__()}.
