It's usually referred to as coderef-@INC, even though there are other things that can be put there. 5.6.1 doesn't "support" anything (it's undocumented) but actually you can only use array refs and code refs there. Calling the INC method on blessed references only came in somewhere in the 5.7 series. Possibly the logic of the tests in 5.8 is wrong - if you put an object in that is a blessed array, it gets treated as "array" (ie fetch element 0 and use it subsequently; pass the whole array in as arguments) rather than "object" I don't think that this ordering is documented.
