Subject: Ruby internals & other questions

Is there a document or website that describes how Ruby works?

For instance ...



y=0
1_000_000.times {|x| y+=x}



(1) Does the block get compiled a million times?

(2) What's the best Ruby way to do a sum from 1 to 1_000_000

(3) Is there a difference in speed between IRB.exe and ruby.exe in
executing the above code?

(4) In IRB, whats the best way to time the code, above?
