... so are Module.const_get and Class.const_get:

class Dog
end

module Stuff
  Greeting = "hello"
end


MyConst = 10

puts Module.const_get("Dog").new
puts Module.const_get("Stuff")::Greeting
puts Module.const_get("MyConst")
puts
puts Class.const_get("Dog").new
puts Class.const_get("Stuff")::Greeting
puts Class.const_get("MyConst")

--output:--
#<Dog:0x251c0>
hello
10

#<Dog:0x25148>
hello
10
