SRFI-42: Runs generator until after expression has evaluated to non-#f. The guarding expression is included in the scope of the variables introduced by the generator.
Note the distinction between :while, stopping at a certain condition, and :until, stopping after a certain condition has occurred. The latter implies that the binding that has triggered termination has been processed by the comprehension.
