sub niler{Nil}; my Int:D $i where .defined = niler(); say $i; say $i.WHAT;
# OUTPUT«(<anon>)(<anon>)»
# expected: well, I don't know since I explicitely asked for a defined
# value _twice_ but Nil is supposed to revert a container to it's default.
# That default is undefined, what can't work with $_.defined and should
# work (by design, not my opinion) with :D.
# Either way, I would like to get a type object when asking for WHAT.
# may be related to RT#127958
