<paragraph>The checked statement causes all expressions in the block to be evaluated in a checked context, and the unchecked statement causes all expressions in the block to be evaluated in an unchecked context. </paragraph>

<paragraph>The checked and unchecked statements are precisely equivalent to the checked and unchecked operators (<hyperlink>14.5.12</hyperlink>), except that they operate on blocks instead of expressions. </paragraph>
