Indeed, I did not mention Bootsnap so as to detract the core point. > That's one of the things Bootsnap does to speedup boot time. And when you do that, there's no compilation at runtime. Correct, if one does `bootsnap precompile`. Bootsnap hooks itself on `Kernel#load` + `Kernel#require` and `RubyVM::InstructionSequence#load_iseq`: https://github.com/Shopify/bootsnap/blob/f627992c52642394311... https://github.com/Shopify/bootsnap/blob/f627992c52642394311... https://github.com/Shopify/bootsnap/blob/f627992c52642394311... https://github.com/Shopify/bootsnap/blob/f627992c52642394311... Essentially this means that it makes LOAD_PATH lookup faster + intercepts iseq compilation to store to cache on a miss and return a cached version on a hit. That does not change the load order. > But that doesn't change anything about OP's suggestion, it's st

ill impossible to know if an interface will ever be implemented. Again correct, as even with `bootsnap precompile` it would only result in earlier ISeq generation (it is essentially cache priming instead of doing it "lazily" on demand), not the time at which these ISeq get loaded and effective, so even then an `abstract` keyword would be ineffective (or rather, equivalent to raising NotImplementedError, i.e syntactic sugar) The only way to do it outside of runtime is with type information, ensuring that only certain types respecting a contract reach the point where the expected interface is made use of. I'm using RBS+Steep, not just for that but this is one of the main reasons and I can attest it does work very well in practice: when the types don't respect the contract it blows up as expected, at which stage raising exceptions is either redundant or a defensive coding mechanism (and I've actually had Steep yell at me because some clauses were unreachable due to types ensuring the contract)

Now, as I think about it, ruby is not like FHS └── gems ├── irb-1.2.3 │ ├── exe │ │ └── irb │ └── lib │ ├── irb │ └── irb.rb └── rack-2.2.2 ├── bin │ └── rackup └── lib ├── rack └── rack.rb vs ├── bin │ ├── irb │ └── rackup └── ruby ├── irb ├── irb.rb ├── rack └── rack.rb FHS approach does not support multiple versions, gems approach requires declaring version in code or Gemfile, playing with PATH, considerable slowdown https://github.com/Shopify/bootsnap

This is a fair point. Yes, I come into lots of issue with Spring autoloader to the point I have a zsh alias call `kill_rails` to make sure it kills all the rails and spring instances :(. That's being said, Spring is an external tool to help solve the slowness of booting up Rails app. I have work in Java/Python and they are slow to bootup too just depend on how big the project is. Tool like: https://github.com/Shopify/bootsnap help to speed up this as well. Other option to look at: https://github.com/danielpclark/faster_path These solves the issue of scanning path, address slowness in a different way compare to preload mechanism of Spring.
