Csn constructors exist in a module object?
Is this code legit in Lua?
1 | local obj = {} |
2 | obj.new = function() |
3 |
4 | end |
5 | return obj |

Yes, it is completely legit. However, you may find it productive to simply return the constructor function unless you have a good reason for needing a table where the only member is a 'new' function.

You can do so.
1 | local obj = {} |
2 | obj.__index = obj |
3 | obj.new = function(val) |
4 | local newobj = {} |
5 | setmetatable(newobj,obj) |
6 | newobj.val = val |
7 | return newobj |
8 | end |
Now, you can create an object of that class.
1 | b = obj.new("string") |
Finally, print out the key called val.
1 | print(b.val) |
string
