Ask HN: Any language that has syntactic support to highlight the main logic?

It beats me why almost all programming language has syntax for comments, but none of them have any syntax to show these are the lines that follow the main logic and every thing else is secondary.<p>If someone is looking at the code it is assumed he understands the syntax. what you really need is to suppress the noise for him to follow the main logic. This would work better than comments as most of the time the comments just repeats what the syntax says with an extra exclamation at the end.<p>If you like the idea pl. up vote. Hopefully new languages like "go" would jump on it.
