Description

I give a useful example for this.

require 'yaml'
env_files = ['config.yml', 'config.local']
envs = env_files.filter_map {|file| YAML.load_file(file)['env'] if File.file?(file) }
ENV.merge!(*envs) # Raise wrong number of arguments (given 2, expected 1)


For now, above code have do like this in ruby 3.0.2

ENV.merge!({}.merge!(*envs))

Hash#merge!(*other) accepts multiple values, so I think it is acceptable.

Matz, how about it?
