I think tied hashes add an unnecessary layer of complexity that doesn't make much sense when you already have objects.

One benefit of tied objects is that, depending on how the class they're tied to behaves, one can slip them in in place of a scalar type, without most of the code knowing the difference. Aside from the well-known example of tying a hash to a DBM file -- transparently moving a hash from in-memory to on-disk, tying can be incredibly handy for some profiling and debugging work, as when you find yourself in the position of needing to count how many times a value gets read or written.
