Well, one example would be incorporating the funtionality of the Env module for arrays, but then on an other level.

An other example would be putting code refs in @PATH which do dynamical lookups. Allowing for the same kind of hooks as supported for @INC and %INC.

But since I understand this is not a 'perl space' operation but lives in an other dimension of the OS, I just do the same stuff with some quick hacks.
