Agreed, but it looks like it adds a layer of syntax to give you things like classes without the user having to leverage metatables.

That is correct. It's also done dynamically so you don't have any external dependencies required when transpiling to Lua code.

EDIT: I am not saying this is better - it could certainly be improved or, as is the case with a project of mine, injected into the runtime as a global value. It's just good for running MoonScript alongside Lua.
