Why does eval "" clear $? when a normal newline doesn't, and it's passed into
and out of eval otherwise?

  $ false
  $ eval ""
  $ echo $?
  0
  $ false
  $
  $ echo $?
  1
  $ false; eval 'echo $?'
  1
  $ eval 'false'; echo $?
  1
  $ if ; then echo hello; fi
  bash: syntax error near unexpected token `;'
  $ if
  > then echo hello; fi
  bash: syntax error near unexpected token `then'

What's the logic here? Probably related to:

  $ if $NONE; then echo hello; fi
  hello
