Perhaps you could tell us what you're really trying to do. This sounds a lot like an XY Problem.

I would rather say an XWTFITL Problem! (Just coined...)

However after some reading futher along this thread I think that the OP would like to "save" a dereferencing chain as a single "entity": of course strictly speaking this is not possible, but a module like Data::Diver which some of us mentioned could come close in functionality. However this makes me wonder about Perl 6.
