Mastodon toot by the author (Filipa Mendonça-Vieira):

After the recent Rubygems drama, I felt anxious, and trapped, frustrated that I can’t escape evil people trying to dominate my life.

I found myself grieving, and mourning the future I grew up thinking we would have; but also feeling hope, that it’s not too late to stop enabling these people, and start choosing kindness.

I wrote about these feelings. Join me in building a better future:

I wasn't able to find any up-to-date information about tail call optimization support in Ruby, so I decided to post this hoping that it will pop up next time someone might also be searching for this topic...

What I was able to figure out is that TCO can be enabled in Ruby 3.4 via a compile option like so:

RubyVM::InstructionSequence.compile_option = {tailcall_optimization: true}

def tailSumUntil(n, m)
  n == 0 ? m : tailSumUntil(n - 1, n + m)
end

tailSumUntil(100_000_000, 0)
# => 5000000050000000

Hi
What is Primitive in the MRI context?

Why did a lot of things get rewritten into Primitive?
Is there some official documentation about it?
