//=========================================================================
// In the retail build, OBJECTREF is typedef'd to "Object*".
// In the debug build, we use operator overloading to detect
// common programming mistakes that create GC holes. The critical
// rules are:
//
// 1. Your thread must have disabled preemptive GC before
// reading or writing any OBJECTREF. When preemptive GC is enabled,
// another other thread can suspend you at any time and
// move or discard objects.
// 2. You must guard your OBJECTREF's using a root pointer across
// any code that might trigger a GC.
//
// Each of the overloads validate that:
//
// 1. Preemptive GC is currently disabled
// 2. The object looks consistent (checked by comparing the
// object's methodtable pointer with that of the class.)
//
// Limitations:
// - Can't say
//
// if (or) {}
//
// must say
//
// if (or != NULL) {}
