It's well known that braces speed up code. That's why VB has always been slower and while K&R chose to ape B when developing C (and why Stroustrup continued the tradition). In fact, check out page 255 in the D&E [1] where Stroustrup provides a little table showing the speed increase (between 9-101%, depending on what you're doing). You don't think that any of us actually *likes* using braces, do you? The VB syntax is *so* much better, but we avoid it due to the speed-up provided by braces.
As it turns out, semi-colons are a modest speed-up as well, which is why the C family of languages uses them as a line termination character instead of as a line separation character the way that Pascal does.
