You could avoid tail calls until the program is debugged.

A tail call arises in this situation:

   return func(x,y,z)
   end

If you don't know how many values func will return, you're stuck with
the tail call.

Otherwise you can do:

   local a,b,c = func(x,y,z)
   return a,b,c
   end

If there is either exactly one return value or it does not matter
to replace return nothing by return nil, it's easier:

   return (func(x,y,z))
   end
