[ruby-core:79895] [Ruby trunk Feature#13272] Keyword argument to instantiate a subclass of Struct

Issue #13272 has been updated by Robert A. Heiler.


I agree it is easier to read.

In the other thread, Shyouhei Urabe said that nobody at the developer
meeting was against it (I assume this also includes matz).

So I suppose that this may be implemented eventually.


----------------------------------------
Feature #13272: Keyword argument to instantiate a subclass of Struct
https://bugs.ruby-lang.org/issues/13272#change-63327

* Author: Satoshi TAGOMORI
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
When we define a subclass of Struct, it take arguments of values of fields when instantiated:

```ruby
ServiceAccount = Struct(:account_name, :full_name, :nickname, :name_invited_by, :twitter_account_name)
a = ServiceAccount.new("tagomoris", "satoshi tagomori", "satoshi", "satoru", "@tagomoris")
```

It's simple and enough easy to use when the code to instantiate it is near from definition.
But sometimes the code using ServiceAccount may be far from definition, and hard to read/understand what does an element represent.

I want to use keyword arguments to instantiate struct objects in such case. it's far easier to understand rather than arguments without keywords:

```ruby
a = ServiceAccount.new(
  account_name: "tagomoris",
  full_name: "satoshi tagomori",
  nickname: "satoshi",
  name_invited_by: "satoru",
  twitter_account_name: "@tagomoris",
)
```
