A couple of the features that we're working towards are subclassibility and multiple engines. Which means DBM::Deep::Array could be subclassed by something that masquerades as an array using Contextual::Return or some other class that overloads @{}. Why should I prevent that when I prefer to use code that ducktypes $_[0] vs. explicit-types it?

My criteria for good software:

Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

Why should I prevent that... Because it leads to lots of debugging and meditations about unexpected pitfalls :) Another possibilty is to create DBM::Deep::Array::Tied and bless tied arrays into that and untied into DBM::Deep::Array. Then you get 2 _get_self()s both of which are crystal clear.	[reply]
