Hi Jared,

> undefined method 'reincarnation' for Map:Class
About this error, Eric has already answered.

But wait a little bit before you go ahead. ;-)
I think you need to know the following two things about Shoes.

1st: Try out this snippet.

class Test
  def hello
    para 'hello'
  end
end

Shoes.app do
  Test.new.hello
end

Yeah,.. it doesn't work well.
You'll get an error "undefined method 'para' for (Test):Test" on the Shoes
Console window.

The following is one of solutions.

class Test
  def initialize app
    @app = app
  end
  def hello
    @app.para 'hello'
  end
end

Shoes.app do
  Test.new(self).hello
end


2nd: Try out another snippet.

Shoes.app do
  def test_run
    stack do
      timer(5){para 'first'}
      timer(3){para 'second'}
      timer(1){return 'third'} # line 6
    end
  end
  ret = test_run               # line 9
  para ret
end

You'll see the output: (Shoes::Stack) second first

Because, timer() method forks a new thread, but doesn't wait for the thread
to end.

And you'll get an error on Shoes Console Window: Unexpected retrun

Because, when Shoes executes the line 6: "return 'third'", the test_run
method at line 9 has already ended.

> I wanted the nice GUI interface to pop up.
Fantastic!
I think Shoes is a good choice!
Although there are a few specific behaviors for GUI programming. ;-)

Let's have fun with Shoes,
