1.9.3 changes the behavior of "rescue else" in a method from previous ruby versions. A return in the method body will not trigger the else.

1.9.2_ex.irb

>> hmm
hello
I got here
in ensure

1.9.3_ex.irb

>> hmm
hello
in ensure

rescue_else_with_return.rb

def hmm
  puts 'hello'
  return
rescue
  puts 'in rescue'
else
  puts 'I got here'
ensure
  puts 'in ensure'
end
