# This class is mutable, but derives from an immutable base, and so
# used to inherit an immutable constructor compiled for the wrong
# class.  It is composed with a Role, and should acquire both the
# attributes in that role, and the initialisers. Likewise for it's own
# attributes. (In the bug this test exhibited, it wasn't acquiring an
# initialiser for 'gristle' or 'yap').
#
# This has now been fixed by adding a check in the immutable
# constructor that the invoking class is the right one, else it
# redispatches to Mouse::Object::new.
