# 8.5. until! expressions

Example 8-5. Example:

    until!(a>10)

    until!_expression ==>
            until!( expression )

until! expressions are iterator calls which take a single boolean argument that is re-evaluated on each iteration. They yield when the argument is false and quit when it is true.
