Nothing.A debugger would be great.

A debugger object, that is availabe in the controller as $this->debugger.

It would only be created, if some debug flag is set to true i.e. in TS, FF
or install tool.

This is resulting in a long call for a quick debug:

$this->controller->debugger->debugIfFieldIsSet('xyz',$fieldname,$var);

Additionally the debugger doesn't know about the current object and its
internal $fields; To solve this another parameter is needed: 

$this->controller->debugger->debugIfFieldIsSet($this, 'xyz',$fieldname
$var);  

Maybe that could be solved by "shortcuts" on the level of tx_lib_object.

$this->debugIfFieldIsSet('xyz',$fieldname,$var);

function debugIfFieldIsSet('xyz',$fieldname,$var) {
  if(is_object($this->controller->debugger))  
      $this->controller->debugger->debugIfFieldIsSet($this, 'xyz'
$fieldname,$var);  
}
