Only in a small rework of `handleAssign()` because that is a place where we conjure a symbol for a new `end()`. I only plan to centralize conjuration of `begin()` and `end()` symbols of containers.

Abstract iterator positions are represented by symbolic expressions because we must be able to do simple calculations with them. This has nothing to do with iterator objects represented as symbols. Or what do you mean exactly by "replacing position symbols with `SymbolMetadata`"?
