Issue #11925 has been updated by k0kubun (Takashi Kokubun).


In case that my suggestion of the name is accepted, I wrote a patch for Struct.new(:a, :b, keyword_args: true).

Feature #11925: Struct construction with kwargs

----------------------------------------
Propose to make Struct subclass constructors which accept keyword arguments. Not sure, if it's reasonable to allow `.new` accept kwargs, so may be should use different method named like `.create`:

```ruby
  Point = Struct.new(:x,:y, :color)
  pt_1 = Point.create(x: 1, y: 2) # => Point<x: 1, y: 2, color: nil>
  pt_2 = Point.create!(x: 1, y: 2) # => ArgumentError, color not specified.
```

It will greatly simplify work with big structures, especially in cases when struct layout changes and for cases when structure can have lots of non-significant values. It also allows simpler ways to use implement default values for struct members.
