If a method in the correct format is provided it will be converted into the conditional block for the Repeater class This expects either one or two method names which will be called against the result of repeating the main block. The correct format is ‘until_<method name>’ or ‘until_<method name>becomes<method name>’.
examples:
until_positive? Attempts to call the :positive? method on the result of the block repeat
until_count_becomes_positive? Attempts to call :count on the result of the block repeat, then :positive? on that result
Calls superclass method
