Subject: Return from ensure

Hi, Rubyists

Actually, I saw a remark on ruby-talk once that "return" is dagerous,
however I could not imagine it is that dangerous. Today I spent 2 hours
debugging the code that looked perfectly normal otherwise. I was able reduce
the code to the following fragment:

def test
  begin
    raise "ERROR"
  ensure
    return "some value"
  end
end

test
puts "Nothing happened"


Yes, it prints out "Nothing happened", and if you comment out "return" you
will see the exception. I just wanted to provide a return value for the
function here, so I naturally used "return" statement. I know that in Ruby
you can return something without explicit "return" and I usually do this
every time. However, at that unfortunate moment my instinct injected
"return" -- and, here we go, 2 hours of fun.

Any comments?

Gennady.
