Error Handling in Ruby

I've recently begun learning Ruby by working my way through the Ruby Koans. I finally made it to the section on error handling, which answered a few questions for me.

Once again, Ruby has not surprised me (this is a good thing). There's just some minor syntactical differences. Specifically in place of "try, catch, finally" Ruby uses "begin, rescue, ensure".

begin
  fail "Oops"
rescue StandardError => ex
  #Do something with the error
ensure
  result = :code_that_always_runs
end 


Since I haven't made it all the way through the koans yet I'm, probably missing something that seems obvious to long time Ruby users, but so far it's pretty damned simple.

    And to think, it only took me nine months to write those few paragraphs!
