To use the control as Sender, at least when it equals the control's OnClick.

At least everything would be more clear, when in the case of different 
control.OnClick and action.Execute the OnClick would take precedence. 
Then it can be assumed that the OnClick handler expects a control, while 
equal handlers more probably indicate and Execute handler, expecting an 
Action as Sender. Then Execute doesn't deserve an override.
