Yes.

I don't think so. We will have a look into that.

Apparently, the problem is related to vararg functions. (A main block
is a vararg function.)

The following is wrong:

  function x (...)
    local <toclose> teste3 = 'stringteste3'
  end
  
  x()
  --> lua: temp:3: attempt to close non-closable variable '(temporary)'

The following is correct:

  function x (a)
    local <toclose> teste3 = 'stringteste3'
  end
  
  x()
  --> lua: temp:3: attempt to close non-closable variable 'teste3'
