Ruby distinguishes between begin/rescue (analogous to Java's try/catch) and throw/catch. I never understood it until discovering that throw/catch is perfect for dealing with nested cases where rescue or break fail. Also, it works through function calls and isn't interpreted as an error, which makes it great for cases like Ramaze's redirect or render calls; unlike in Rails, they interrupt execution immediately.
