    Compile-time Behavior:

    A block is a possibly-empty sequence of statements surrounded by curly braces.
    Any declaration or definition within the block must not be visible outside of the block.

    Runtime Behavior:

    When a block is executed, each of the containing statements, in linear order, is executed.
