title: "@for"
introduction: >
The `@for` rule, written `@for <variable> from <expression> to <expression>
{ ... }` or `@for <variable> from <expression> through <expression> { ... }`,
counts up or down from one number (the result of the first
[expression](../../syntax/structure#expressions)) to another (the result of
the second) and evaluates a block for each number in between. Each number
along the way is assigned to the given variable name. If `to` is used, the
final number is excluded; if `through` is used, it's included.
