Place: Cookpad Inc. (Tokyo, Japan)

Please comment your favorite ticket numbers you want to ask to discuss with your SHORT comment or summary.
(your summary/comment will help us because we don't need to read all of ticket comments)

DO NOT discuss then on this ticket, please.

From this time, we use a ticket to make dev-meeting agenda page instead of a wiki page https://bugs.ruby-lang.org/projects/ruby/wiki.

NOTE

Dev meeting IS NOT a decision making place. All decisions should be done at the bug tracker.
Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly.
Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue).
We will write a log about discussion to a file or to each ticket in English.
All activities are best-effort (keep in mind that most of us are volunteer developers).
The date, time and place is scheduled according to when/where we can reserve Matz's time.

From non-attendees

  • [Feature #14697] Introducing Range#% as an alias to Range#step (mrkn)
    • Matz already commented LGTM. Please judge whether this is acceptable.
  • [Feature #14724] chains of inequations (mrkn)
    • This new syntax can also reduce the duplicated evaluations of common terms, such as timeval.tv_sec in the descriptiohn of the proposal.

Functional programming: (zverok)

  • [Feature #6284] Add composition for procs
    • 6-year-old proposal. Matz: "Positive about adding function composition. But we need method name consensus before adding it? Is #* OK for everyone?"
  • [Feature #13581] Syntax sugar for method reference
    • 1-year-old proposal. Matz: "I am for adding syntax sugar for method reference. But I don't like proposed syntax (e.g. ->). Any other idea?"
  • [Feature #11161] Proc/Method#rcurry working like curry but in reverse order
    • 3-year-old proposal with absolutely no reaction. I've added real-life examples there several months ago.
  • [Feature #14390] UnboundMethod#to_proc
  • [Feature #14423] Enumerator from single object (Object#enumerate)

Misc:

  • [Bug #14575] Switch Range#=== to use cover? instead of include? (zverok)
