You need to use the setglobal tagmethod (Lua 4) or the __newindex
metamethod on the global table (Lua 5). The key provided as the argument is
the name of the global.

Alternatively, you could do this:

function MyObject(name)
  -- construct the object however you want to.
  getglobals()[name] = newobject
  return newobject
end

and then call it like this:

MyObject "object_1"

which would have the side_effect of setting the global object_1.

I think the first solution is cleaner but I use the second one in some
configuration files because it looks better.
