Five lines that turn Ruby into a different language

gistfile1.rb

class Object
  def method_missing m, *args
    Object.respond_to?(m, true) ? Object.send(m, self, *args) : super
  end
end

What is this about? Newbie in ruby

No, object structure change does not change the language.

solojavier: It allows you to chain functions onto arbitrary objects. Each function that you use in this style is understood to accept the return value of the previous link in the chain as its first argument. I know that is abstract, but here is a code example:

def plus array, n
  array.map { |x| x + n }
end

[1,2,3].plus(1).plus(2) == [4,5,6]

ArrayMac: A language is a set of conventions around expression. The term DSL (Domain-Specific Language) uses the word 'language' in this sense.

I would use the term 'constrained' not 'different' for a DSL, but that's just me.
