-// The "shape" of a type is best defined as "how a value of a type looks from
-// the standpoint of a certain built-in operation".
-//
-// This is used to collapse take/drop glues that would otherwise be
-// separate. For instance, a boxed tuple of 3 ints and a boxed tuple of 3
-// uints look the same as far as reference count manipulation is concerned, so
-// they get the same shape so that their reference count glues can be
-// collapsed together. To give another example, an int and float have the
-// same (nonexistent!) glue as far as reference counting is concerned, since
-// they aren't reference counted.
