table entry qualifies as an lvalue because it can be both read and changed. To
qualify as an lvalue, text must exactly specify the storage location referred
to: "Table of Corvettes" only indicates a table, not an entry in a table, so
is merely an rvalue. Similarly, "carrying capacity" (as a property name not
indicating an owner) is a mere rvalue.
