 * @assertion An expression of the form [e as T] is accepted as a potentially
 * and compile-time constant expression if [e] is potentially constant or
 * compile-time constant, respectively, and [T] is a compile-time constant type.
 * A compile-time constant type means any type that doesn't contain free type
 * variables, so the type expression always resolves to the exact same type.
 * @description Checks that an expression of the form [e as T] is not accepted
 * and causes compile time error if [e] is not a compile-time constant and it's
 * assigned to the [String] variable.
