Still in section "3.3.8 - To-be-closed Variables", about several
closing method errors:
To quickly test in the Lua REPL, I did:
> smt = getmetatable('a')
> function function smt.__close(s) error("err closing ".. s) end
Test with one error:
> do local <toclose> x='XX' end
stdin:1: err closing XX
stack traceback:
[C]: in function 'error'
stdin:1: in function <stdin:1>
stdin:1: in main chunk
[C]: in ?
Test with two errors:
> do local <toclose> x='XX'; local <toclose> y='YY' end
stdin:1: err closing XX
No stack traceback. Is it normal?
