/// @assertion Evaluation of a throw expression of the form throw e; proceeds as
/// follows:
/// The expression e is evaluated yielding a value v.
/// If v evaluates to null, then a NullThrownError is thrown. Otherwise, control
/// is transferred to the nearest dynamically enclosing exception handler, with
/// the current exception set to v and the current return value becomes
/// undefined.
///
/// NNBD Spec: It is an error if the static type of [e] in the expression [throw
/// e] is not assignable to [Object].
///
/// @description Checks that attempting to throw null in any manner results in
/// NullThrownError being thrown instead.
