@ -48,8 +48,9 @@ conservative route. We are likely to relax this restriction in the future.
## Drawbacks
Adding a new function to `table` library theoretically increases complexity. In practice though, we already effectively implement `table.clone` internally for some VM optimizations,
so exposing this to the users bears no cost.

Assigning a type to this function is a little difficult if we want to enforce the "argument must be a table" constraint. It's likely that we'll need to type this as `table.clone(T): T` for the time being, which is less precise.
## Alternatives
