[ruby-core:111254] [Ruby master Feature#12813] Calling chunk_while, slice_after, slice_before, slice_when with no block

Issue #12813 has been updated by sawa (Tsuyoshi Sawada). I think this has already been implemented by now. It should be closed. ---------------------------------------- Feature #12813: Calling chunk_while, slice_after, slice_before, slice_when with no block https://bugs.ruby-lang.org/issues/12813#change-100548 * Author: marcandre (Marc-Andre Lafortune) * Status: Assigned * Priority: Normal * Assignee: matz (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/
