Hi, the following code from "symbol.h"

#if defined(HAVE_STMT_AND_DECL_IN_EXPR)
/* __builtin_constant_p and statement expression is available
* since gcc-2.7.2.3 at least. */
#define rb_intern(str) \
(RBIMPL_CONSTANT_P(str) ? \
__extension__ ({ \
static ID rbimpl_id; \
rbimpl_intern_const(&rbimpl_id, (str)); \
}) : \
(rb_intern)(str))
#endif

#endif /* RBIMPL_SYMBOL_H */

uses

static ID rbimpl_id;

just to provide storage for the ID, why?
