Puppet users - Dec 2012 - Proper way to call variables from a parent class to a child class

I currently have a child class of a parent one.  The parent defines 
some variable that I need to use in the child class.  I am also using 
gepetto.  Gepetto is complaining about the syntax of the child variable. 
 It is saying that "$parentVar" should be "$::parentVar"
however, when
changing to what Gepetto wants to use this breaks my classes.  Does anyone 
know the proper method of doing this?  Currently the "$parentVar"
method
below works fine, its just causing an error with Gepetto.

class test::parent {
$parentVar = "abc"
include test::child 
}

class test::child {
notify { "The variable is: $parentVar":}
}

Hi there,

This is an example of dynamic scoping, and there is a good help document
here --> http://docs.puppetlabs.com/guides/scope_and_puppet.html  That page
should describe what you''re seeing and how to clarify it.

Understandable, thank you for that clarification.  The issue I am facing 
comes when I am using a define and I need to call that custom variable set 
in another class that calls the define.  Please see the example below. 
 Though this works as I want it to below, I am getting a syntax error.  If 
I chang the variable in class test to "$test::define::defVar", breaks
what
I want it to do.  Am I breaking some style guidelines in doing what I want 
to do?  Is there another way I can call this defined variable without 
producing a syntax error?

class test {
notify {"!!!!!!!!!!!!!!!!!!!The variable inside test main class is 
$defVar":}
}

define test::define($defVar=''defVar''){
include test
notify {"the variable in define define is: $defVar":}
}

class test::stuff::test1{
test::define {''test1'': defVar =>
''NEWDEFVAR''}
}

In this case, using $defVar inside test::define is completely fine because
it''s defined in the scope of this defined resource type ($defVar is in
the
parameter declaration section of the defined resource type, which makes it
local, in scope, to this defined resource type).  Even though the class
class test::stuff::test1 is declaring a new resource of type test::define,
it''s passing a value (''NEWDEFVAR'') which will get set
INSIDE the scope of
test::define as $defVar.

I hope that made sense and helped you; it can become a complicated issue
quickly :)
