A snippet to add to your .pryrc so refinements work at top level

.pryrc

Tempfile.new('pry-binding').tap do |binding_chord|
  binding_chord << 'Pry.toplevel_binding = binding'
  binding_chord.close
  load binding_chord.path
ensure
  binding_chord.unlink
end

al203-cr.rb

# derived from al203-cr's solution in the #ruby IRC channel

Pry.hooks.add_hook :when_started, :context_switch do |_output, _binding, pry|
  pry.binding_stack = [TOPLEVEL_BINDING]
end
