[ruby-core:87082] [Ruby trunk Misc#14698] DevelopersMeeting20180517Japan

Issue #14698 has been updated by ana06 (Ana Maria Martinez Gomez).


@shyouhei

>  I think there are chances for us to welcome only one person but very skeptic if it works for, say, 20 people. The meeting obviously does not scale. What to do then? We have to select someone by something? That doesn't sound well.

Well, if nobody else asked until now to join the meeting, maybe nobody also asks it in future. And it is not a problem that exist at the moment. ;)

Anyway, if it is not possible that I join, I completely understand it. I am already happy that there is a discussion about those issues. :)

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.

# Agenda

## 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)
