Greetings,

I've been trying to tinker with a global Cache module, but I can't figure out why this isn't working.

Does anyone have any suggestions?

This is the error produced for the below code:

NameError: undefined method get' for moduleCache' from (irb):21:in `alias_method'

module Cache

  def self.get
    puts "original"
  end

end

module Cache

  def self.get_modified
    puts "New get"
  end

end

def peek_a_boo

  Cache.module_eval do
    # make :get_not_modified
    alias_method :get_not_modified, :get
    alias_method :get, :get_modified
  end

  Cache.get

  Cache.module_eval do
    alias_method :get, :get_not_modified
  end
end

# test first round
peek_a_boo

# test second round
peek_a_boo

TIA!
