Creates a new table with the same top-level key-value pairs as the original without duplicating nested tables.

Lua

function shallowcopy(t) local copy = {} for k, v in pairs(t) do copy[k] = v end return copy
end

so does that mean you're doing a shallow copy but skipping nested recursion? what happens if the original has metatables - are they preserved or transferred to the new table?
