this question has reply here:

methods in ruby: objects or not? 5 answers what recursive arrays for? 2 answers

ended accidentally doing equivalent of in ruby other night:

class="lang-ruby prettyprint-override">a = *1..5 # => [1, 2, 3, 4, 5] << a # => [1, 2, 3, 4, 5, [...]] a.last # => [1, 2, 3, 4, 5, [...]]

what [...] , can it?

it's way array.inspect displays recursive arrays. lastly element of itself. if displayed after 5, inspect end in endless loop:

[1, 2, 3, 4, 5, [1, 2, 3, 4, 5, [1, 2, 3, 4, 5, [1, 2, 3, 4, 5, [...]]]]]
