Everytime you call lua_pushstring() a new string is pushed onto the

Only true if the string is new to Lua.
I thought that string interning was an implementation detail not really
to be relied upon. Are you going to guarantee that if I pushstring the
same character sequence I get identical pointers when I tostring them?
lua_pushstring(l, "hello");
lua_pushstring(l, "hello");
p = lua_tostring(l, -1);
q = lua_tostring(l, -2);
c = (p == q);
So you guarantee that c=1 ?
