What is Ruby?
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.
Features of Ruby
Simple Syntax
Normal Object-oriented Features (e.g. class, method calls)
Advanced Object-oriented Features (e.g. mix-in, singleton-method)
Operator Overloading
Exception Handling
Iterators and Closures
Garbage Collection
Dynamic Loading of Object Files (on some architectures)
Highly Portable (works on many Unix-like/POSIX compatible platforms as
well as Windows, macOS, etc.) cf.
https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers

3 points · Open discussion> a very good subset of Ruby could be implemented with a similar-sized code base than Lua
That would have to be quite the subset. The Ruby parser alone is almost 12kLOC. I've implemented entire languages in 1/10th that.

7 points · Open discussionI think it's on a right track to be quite something, which is why I wanted to try it out & mention that on HN.
It's interesting to note that on the "classic" Ruby, there is work ongoing in 2.6 to accelerate it quite a bit (MJIT). The current PR for this is there:
https://github.com/ruby/ruby/pull/1782
Even before that, Ruby is getting faster, you'll get running times from 2.0.0 to 2.5.0 for a little benchmark I made here:
