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.

Past meetings: https://bugs.ruby-lang.org/projects/ruby/wiki#Developer-Meetings

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.

Agenda

Next dev-meeting

About 2.6 timeframe

Carry-over from previous meeting(s)

• [Feature #14784] One-sided Comparable#clamp (with endless/startless ranges) (zverok)
  • more reasonable version of Object#enumerate proposed for the previous meeting.
• [Feature #14859] Timeout in VM (normalperson)
  • Still needs some work, mainly wondering if the idea of moving this part of stdlib into core VM is acceptable or not. No semantic changes except speed improvement.
