Subject: Benchmark obsession?

Hi,

After having read this list for a while, I wonder why some of you put so
much weight on speed optimizations. I'm not talking about big things
that really make sense but small stuff like "Don't use symbols, they
can't be garbage collected", "Don't concatenate strings, use string
interpolation instead", "Don't use Enumerable#inject to build up
objects" etc. etc.

In my opinion, this is like trying to get a classic car faster. It just
makes no sense. Ruby isn't about speed, it's about elegance and clarity.
If you're looking for speed, you've got the wrong language. Use C or
whatever.

I'd always prefer an elegant solution over a fast one. For example, I
love functional style programming with Enumerable#inject. I don't care
if it's some milliseconds slower than assigning the values to a
variable.
