/// @assertion Any expression that appears within the initializer list of a
/// constant constructor must be a potentially constant expression, or a
/// compile-time error occurs.
///
/// A potentially constant expression is an expression E that would be a valid
/// constant expression if all formal parameters of E's immediately enclosing
/// constant constructor were treated as compile-time constants that were
/// guaranteed to evaluate to an integer, boolean or string value as required
/// by their immediately enclosing superexpression.
/// @description Checks that it is a compile-time error when a constant
/// constructor's initializer list contains a function call.
