Stefan, while I agree that in general you should write a proper class,
the case I was talking about is a completely valid and normal use of
multi-dimensional arrays in ruby.  I'm guessing that duplicating a row
in an array is not a rare occurrence either.  I was just saying that
maybe a mention of this should be added to the standard docs, as it's
a common pitfall.  Bits are cheap :) common pitfalls should be noted
all over the place in the docs.
