Action: Stop evaluting other rules

It would be nice to have a new 'Action: Stop evaluting other rules' to avoid other rules to be fired after the current.
For example take two rules, first has condition New user registration and redirects to a specific path, the second has condition User logged in and redirects to another path.
After user registration user is also logged, but i do not want to fire both rules. So I think this new action would solve this problem. Sure there are also other situations where a stop condition would be userful.
