comments

C2 comments work in the same way as C's. Thus both forms are available:

// a one line comment
/* A
   multi-line
   comment
*/

semi-colons

Every statement in C2 is followed by a semicolon, except when it ends with a right-hand brace: } !! Trailing attributes never change the rule above.

That means you will never see };. Makes it easier on the eyes ;)
