Issue #17290 has been reported by sawa (Tsuyoshi Sawada).
----------------------------------------
Feature #17290: Syntax sugar for boolean keyword argument
https://bugs.ruby-lang.org/issues/17290
* Author: sawa (Tsuyoshi Sawada)
* Status: Open
* Priority: Normal
----------------------------------------
We frequently use keyword arguments just to pass `true` value out of the truthy/falsy options given. And in many such cases, the falsy option is set as the default, and only the truthy value is ever passed explicitly. I propose to have a syntax sugar to omit the value of a keyword argument. When omitted, it should be interpreted with value `true`.
```ruby
gets(chomp:)
CSV.parse(" foo var ", strip:)
```
should be equivalent to
```ruby
gets(chomp: true)
CSV.parse(" foo var ", strip: true)
```
Additionally, we may also extend this to pragmas.
```ruby
# frozen_string_literal:
```
to be equivalent to:
```ruby
# frozen_string_literal: true
```
