Comments

FunC has single-line comments which start with ;; (double ;). For example:

int x = 1; ;; assign 1 to x

It also has multi-line comments which start with {- and end with -}. Note that unlike in many other languages, FunC multi-line comments can be nested. For example:

{- This is a multi-line comment
    {- this is a comment in the comment -}
-}

Moreover, there can be one-line comments inside multi-line ones, and one-line comments ;; are "stronger" than multiline {- -}. In other words in the following example:

{-
  Start of the comment

;; this comment ending is itself commented -> -}

const a = 10;
;; this comment begining is itself commented -> {-

  End of the comment
-}

const a = 10; is inside multiline comment and is commented out.
