As the dual of Liftable, the concept should be named Unliftable.
Additionally when programmers did not know about ValueOfExpr, they have been asking is the was
an unliftable/unlift.
For a future PR: Should the
Value.unapply
extractor be renamed toUnlift.unapply
orExpr.unapply
(asExpr.apply
is lifting)? See #8504
