Using a module in a `rescue` clause; based on https://ptb.discord.com/channels/518658712081268738/766466740069859349/1243630842073321483

module-scoped rescue.rb

# Marker module for “my library”
module MyError end

# Built-in exception class example
ZeroDivisionError.include MyError
puts begin
  1 / 0
rescue MyError => e
  e
end #=> divided by 0

# Custom exception class example
class APIError < RuntimeError
  include MyError
end
puts begin
  raise APIError, 'oof'
rescue MyError => e
  e
end #=> oof

# Non-match example
puts begin
  0 + ''
rescue MyError => e
  e
