// /decl is a subtype used for singletons that should never have more than one instance
// in existence at a time. If you want to use a /decl you should use a pattern like:
// var/decl/somedecl/mydecl = GET_DECL(/decl/somedecl)
// /decls are created the first time they are fetched from decls_repository and will
// automatically call Initialize() and such when created in this way.
// decls_repository.get_decls_of_type() and decls_repository.get_decls_of_subtype()
// can be used similarly to typesof() and subtypesof(), returning assoc instance lists.
// The /decl commandments:
// I. Thou shalt not create a /decl with new().
// II. Thou shalt not del() or qdel() a /decl.
// III. Thou shalt not write a decl that relies on arguments supplied to New().
// IV. Thou shalt not call Initialize() on a /decl.
