/* This template produces a unique symbol definition for an explicit
template instantiation (without also incorporating a reference),
and an extern template declaration can be used to reference that
symbol from another object. The modid parameter is just a
placeholder to create different symbols (because it affects the
name mangling of the static value member). By convention, it
should match the number of the module that contains the
definition. */
