#### 3.2.7 Blocks

Any sequence of drawables may be grouped in a block merely by enclosing them in braces { }. A block is itself drawable. A key use of blocks is to extend the effect of a single `def`, Definitions, `put` Puts, `sweep` Sweeps, or `repeat` Repeats to include several objects rather than one.

Definitions (See Definitions.) inside a block have lexical scope extending from the place of definition to the end of the block.
