How to cancel evaluating a required Ruby file? (a.k.a. top-level return)

Question

file1 requires file2, and I want to be able to cancel evaluating file2 under certain conditions without exiting the whole process.

Answer 1

Is using a method possible ? It will still parse the method but won't get executed. Something like :

#file1.rb
  puts "In file 1"
  require 'file2'
  puts "Back in file 1"
  a_method

#file2.rb
  puts "In file 2"
  # <= A

  def a_method
    puts "Still in file 2"
  end
