That's true.
btw, the browser uses it when choosing 'toggle break on entry' for a method.

Right, but still, the two methods shouldn't have the same name. I look 
at #break as at #halt which I can also send to any receiver to get what 
I want.
But sending #breakpoint instead of #break would be fine for me.
