raise / rescue is for error handling. catch / throw is for control
flow. catch / flow is especially useful if you have multiple exits for
a piece of code.  Although I have to say I rarely felt the need for
this. Basically it's the same as a method with multiple "return"s only
you do not leave the current scope.

Kind regards
