Method SetField

lua.go:481–487

SetField does the equivalent of table[key]=v where table is the value at index and v is the value on top of the stack. This function pops the value from the stack. As in Lua, this function may trigger a metamethod for the __newindex event. http://www.lua.org/manual/5.2/manual.html#lua_setfield

	l.push(key)
	l.setTableAt(t, key, l.stack[l.top-2])
	l.top -= 2
