 are located in storage, even though they also have type ``uint[]``.  However,
 if ``d`` was assigned, we would need to clear knowledge about ``array`` and
 vice-versa.

+Real World Assumptions
+======================
+
+Some scenarios can be expressed in Solidity and the EVM, but are expected to
+never occur in practice.
+One of such cases is the length of a dynamic storage array overflowing during a
+push: If the ``push`` operation is applied to an array of length 2^256 - 1, its
+length silently overflows.
+However, this is unlikely to happen in practice, since the operations required
+to grow the array to that point would take billions of years to execute.
