Can you elaborate on your claim? How inefficient, like, by orders of
magnitude? Is it serious enough to affect the overall performance of a
typical ruby application? In a situation like this, I'd prefer the
code which uses 'inject', since it shows the intention of the
programmer more clearly and concisely, while the performance penalty -
10% in my naive experiment - is irrelevant in this case. I agree that
we should be aware of the performance issues even when we're dealing
with a high-level language such as ruby, but your bold statement makes
me feel that you're trying to 'defend' your own code against the
others in some kind of a code contest.
