conciseness vs. readability

To print the contents of all files passed as arguments or in case of no arguments print the contents of stdin you could write

puts *ARGF

but isn’t

if ARGV.empty?
  puts $stdin.readlines
else
  ARGV.each do |filename|
    puts File.readlines(filename)
  end
end

much more readable?
