Subject: Why stack can hold indefinite objects but records cannot?

Why is it OK to create an indefinite object as a local variable ("on stack")
but not OK to put an indefinite object into a record?
How records are less powerful than the stack?
By the way, how indefinite local variables can be implemented? (just
curious)
Moreover, wouldn't it to be a good idea to allow indefinite objects in
records (thus making the record itself indefinite, even if it has no
discriminants)? I realize that then it would be difficult to track which
records are definite and which indefinite. But what's about the idea?
