Okay. Assuming that I'm going to try and make TimeZone opaque within SysTime, does that require a pointer rather than a reference? And I assume then that the time zone stuff would need to be in a separate module than SysTime. That being the case, how would SysTime be able to use the time zone without importing that module? Does the C++ solution of forward declaring it like
class TimeZone; work in D? - Jonathan M Davis
