Yes Adam, you explain the problem very well.

I still fail to see the bug. What is the problem if the error reported is a real error in 'fclose' instead of the previous error

Obviously I disagree with Roberto :-)

The function must return the first error condition, any other solution is unreliable so useless.

I am a newbie in the "Lua ecosystem".

Every software has bugs, big and small.

Lua is an excellent tool; we can only improve it.

An error in closing the file after an error has already occurred on the file is highly likely to be spurious -- after a file has had a critical error that would warrant closing the file handle unconditionally, you really can't trust its state, so any error that comes up while trying to clean it up probably isn't helpful.
