- Blocks are one or more expressions grouped together with curly braces. Each - expression is evaluated in order and the value of the last expression is - returned. -

-

- Any variables assigned within the block can only be used within the block. -

-

- Try uncommenting io.debug(degrees) to see the compile error from - trying to use a variable that is not in scope. -

-

- Blocks can also be used to change the order of evaluation of binary operators - expressions. -

-

- * binds more tightly than + so the expression - 1 + 2 * 3 evaluates to 7. If the 1 + 2 should be - evaluated first to make the expression evaluate to 9 then the expression can be - wrapped in a block: { 1 + 2 } * 3. This is similar to grouping - with parentheses in some other languages. -
