                //
                //  1. The Project N toolchain aggressively replaces static constructors with static initialization data whenever possible.
                //     So the static constructor may no longer exist.
                //
                //  2. Invoking the static constructor through Reflection is not very useful as it invokes the static constructor whether or not
                //     it was already run. Since static constructors are specifically one-shot deals, this will almost certainly mess up the
                //     type's internal assumptions.
