I propose adding a `#size=` method for truncating without allocating a new array: ``` a = [10, 20, 30] a.size = 2 a # [10, 20] ``` Growing the array could be allowed as well... ``` a = [10, 20] a.size = 4 a # [10, 20, nil, nil] ``` -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
