#define HFIRSTNODE 3
/*
** Besides these values, pset (pre-set) operations may also return an
** encoding of where the value should go (usually called 'hres'). That
** means that there is a slot with that key but with no value. (pset
** cannot set that value because there might be a metamethod.) If the
** slot is in the hash part, the encoding is (HFIRSTNODE + hash index);
** if the slot is in the array part, the encoding is (~array index).
** 'luaH_get*' operations set 'res' and return HOK, unless the value is
** absent. In that case, they set nothing and return HNOTFOUND.
** The 'luaH_pset*' (pre-set) operations set the given value and return
** HOK, unless the original value is absent. In that case, if the key
** is really absent, they return HNOTFOUND. Otherwise, if there is a
** slot with that key but with no value, 'luaH_pset*' return an encoding
** of where the key is (usually called 'hres'). (pset cannot set that
** value because there might be a metamethod.) If the slot is in the
** hash part, the encoding is (HFIRSTNODE + hash index); if the slot is
** in the array part, the encoding is (~array index), a negative value.
** The value HNOTATABLE is used by the fast macros to signal that the
** value being indexed is not a table.
