Ruby is an interpreted object-oriented programming language often used
for web development.  It also offers many scripting features to
process plain text and serialized files, or manage system tasks.  It
is simple, straightforward, and extensible.

Ruby 4.0 introduces a number of new features and performance improvements,
here are some of them:
  * Ruby Box

	a new (experimental) feature to provide separation about definitions

  * Performance: ZJIT

	a new just-in-time (JIT) compiler, which is developed as the
	next generation of YJIT

	It is not enabled on pkgsrc for now.

  * Ractor Improvements
  * Stdlib updates
  * Retirement of RJIT: Experital pure-Ruby JIT compiler
