In role Iterator§
See primary documentation in context for method skip-at-least
method skip-at-least(Iterator: , int --> Mu)
Should skip producing $to-skip
values. The return value should be truthy if the skip was successful and falsy if there were not enough values to be skipped:
my = <a b c>.iterator;say .skip-at-least(2); say .pull-one; say .skip-at-least(20);# OUTPUT: «1c0»
The Iterator role implements this method as a loop calling skip-one
and returning whether it returned a truthy value sufficient number of times.
