I've added a pull request that fixes this issue: https://github.com/ruby/ruby/pull/3157 It's not a perfect fix, but a perfect fix would require disabling a commonly used optimization, resulting in additional array allocations in common cases when using splatting with block passing. ---------------------------------------- Bug #16504: `foo(*args, &args.pop)` should pass all elements of args https://bugs.ruby-lang.org/issues/16504#change-85860 * Author: mame (Yusuke Endoh) * Status: Open * Priority: Normal * ruby -v: ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux] * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN ---------------------------------------- https://bugs.ruby-lang.org/issues/16500?next_issue_id=16499&prev_issue_id=16501#note-7 ``` # in 2.7 args = [1, 2, -> {}]; foo( *args, &args.pop) #=> passes [1, 2] (bug; [1, 2, ->{}] is expected) args = [1, 2, -> {}]; foo(0, *args, &args.pop) #=> passes [0, 1, 2, ->{}] (good) ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
