gistfile1.txt

require 'watir-webdriver'

class BrowserProxy
  instance_methods.each { |m| undef_method m unless m =~ /(^__|^send$|^object_id$)/ }


  def my_awesome_method
    "you just called an awesome method!"
  end

  def initialize(browser = :firefox, *args, &block)
    @target = Watir::Browser.new(browser, *args, &block)
  end




  def method_missing(name, *args, &block)
    @target.send(name, *args, &block)
  end

end

proxy = BrowserProxy.new
real = Watir::Browser.new

test = "VARIABLE IN SCOPE"
real.instance_eval "puts(test)"
proxy.instance_eval "puts(test)"

##output:
