Well.. that's why I said it's an interesting question :)
I don't think it should be a language check. It should be plumbed into the type
system code.. somehow. Currently `ValueObject::Dereference` calls
`GetCompilerType().GetChildCompilerTypeAtIndex` (which eventually calls into
the type system). That's kind of a problem because the type system doesn't
actually know that it's being asked to dereference. Nonetheless, after it
returns, it does tell you whether the returned child is a dereference of the
parent (via the `child_is_deref_of_parent` by-ref result).
So, one option that *might* be acceptable (to me, others may disagree) would be
to call this function on array types as well and then to check whether the
result has the `child_is_deref_of_parent` flag set (we'd also need to change
the TypeSystemClang implementation so that it sets the flag for the first
element of the array).
The alternative would be to create a new function that explicitly tells the
type system that you're trying to dereference the value, and then it can do
pretty much anything it wants.
