Thank you, this was great! Both my work and side projects all run on Ruby (except the ones that run on js), and this has been extremely helpful. I actually wrote def(whatever, &block) ... all the time because I was told that it would be clearer that a block was needed, but if just dropping the &block means I can get a 4x speed upgrade... well, time for a bit of refactoring in various critical loop sections.

> if just dropping the &block means I can get a 4x speed upgrade Well, up to 4x. If you're doing anything interesting or complex, or, god forbid, making a database call, then this might turn into an instance of that famous anecdote where Bill Gates wouldn't even bend over to pick up a thousand dollars laying on the ground.

  This can't be emphasized enough. Do almost anything worth doing in that function or in the block itself and the 400% improvement on the 1% of that functions execution time becomes almost certainly meaningless. These kinds of performance improvements have very steep diminishing returns.
