It does not. The most viable solution is transpilation, teal is the most recent candidate.
You can have a hack of sorts using a schema and tables as in
local schema = { a = "number", b="string" } -- key = "type"
local data, link = {a=4, b="default value"}, {} -- link -> data, link itself is always empty
local tbl = setmetatable(link, {
__index = data
, __newindex = function (t,k,v)
if schema[k] and type(v)==schema[k] then data[k] = v return true end
error"type does not match schema"
end
})
tbl.b = 5 -- this will error because its the wrong type
There are certain solutions you can do with functions, lsp is also really good at telling you when you went wrong.
