Issue #12813 has been reported by Marc-Andre Lafortune. ---------------------------------------- Feature #12813: Calling chunk_while, slice_after, slice_before, slice_when with no block https://bugs.ruby-lang.org/issues/12813 * Author: Marc-Andre Lafortune * Status: Open * Priority: Normal * Assignee: Yukihiro Matsumoto ---------------------------------------- Currently, `chunk_while`, `slice_after`, `slice_before`, `slice_when` all require a block. If one needs the index within the block, there is no good way to do this; `enum.each_with_index.chunk_while` would have indices in the results, so `enum.enum_for(:chunk_while).with_index` is the best solution. I feel that we should return `enum_for(:chunk_while)`. This is strictly more useful than raising as we currently do. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
