/// @assertion Calling a redirecting factory constructor k causes the
/// constructor k' denoted by type (respectively, type.identifier) to be called
/// with the actual arguments passed to k, and returns the result of k' as the
/// result of k. The resulting constructor call is governed by the same rules
/// as an instance creation expression using new.
/// @description Checks that a call to redirecting factory constructor indeed
/// results in a call to referenced constructor with the same actual arguments.
/// Test type aliases
