warning: method redefined; discarding old require about bootsnap HOT 2 CLOSED

I wonder if you could turn this into a module that is #prepend to Kernel?

No it's not possible because rubygems uses a similar alias_method chain, and it doesn't mix well with prepend. Zeitwerk also alias method chain require, so we'd need to coordinate all this which is practically not possible.

In the meantime I can silence that warning using the alias_method trick:

module Kernel
  module_function

  alias_method :require, :require
  class << self
    alias_method :require, :require
  end

  def require(path)
  end
end

It's just weird I never noticed that warning before.

Understood, thanks for taking the time to explain!
