I think that you have nailed it here. I don't think anyone on this list is capable of giving a "concrete" (as you have put it) operational definition of "inhomogenous". They will resort to use cases and thus cloud the definition with programming philosophy. So, programming philosophy, whether it will be admitted or not, is fully responsible for the exclusion of index() from the tuple interface. But perhaps we could take "not necessarily homogenous" to be the operational definition of "inhomogenous". Of course then we would have to define necessary...
