If you haven't noticed unless I have a certain goal and it is a really
popular codec I just don't really care about speed.
I only point out the really blatant things, and I think that's not a waste
of time since it should mean the original author learns something worth
learning because it can be applied often.
Unless you mean "micro-optimizing for readability", in which case I simply
hope it will still help with the big optimizations if necessary :-)
