I would agree with you in general, but since we're generally after speed,
surely we want to allow for optimisations such as "don't store unless

My idea of "visible" is that it would make a lexically scoped thing

By default that would only apply to $_, but the mechanism should be

The relationship to the array/list thing is this: that it's not just

All this is orthogonal to the concept of "object": in C++ "an object" can be
