This enables proper OOP implementation in Lua.
setmetatable
is much safer then I had been thinking (I had mentally swapped it with what you can do withdebug.setmetatable
which is unsafe. This allows us to do proper OOP stuff such as what's depicted here. This replaces the sytle shown here: #14350. The significant win of this is that this enabled object oriented usage without using nearly as much memory for each object.
