Ruby: The future of frozen string literals

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

Some examples:

7 # integer literal

tompng

require 'io/console'
require 'pty'

command = ARGV.join(' ')
if command.empty?
  puts 'Error: Command not specified.'
  puts "Usage: `ruby #{File.basename __FILE__} options -- command`"
  exit
end
