You're putting arrays into a hash. When you put something into a hash, it matters whether the object in question has *reference nature* or *value nature*. * If it has reference nature, the *reference* is used as the hashable thing. * If it has value nature, the *value* (i.e. contents) is used as the hashable thing. It is important for the hash that whatever we use as the hashable thing won't change over time. (Because if it does, then we won't find the object again when we look for it later.) The value/contents of an array can change over time, and therefore it cannot have value nature, and therefore Perl 6 uses the reference to hash arrays, and therefore you get three distinct things. Hope that helps. // Carl
