I have to say this is such a really neat hack...  it says so much
about Ruby too.

I had a hard time understanding it until I realised that the first
END_REEVAL doesn't need to be in quotes.  Writing it as:

    eval("<<END_REEVAL\n" + self + "\nEND_REEVAL\n", b)

seems to work just as well.  Any reason you did it that way?
