Issue #5027 has been updated by Paul Berry.
Here is an example of a .pp file that should produce the warning:
<pre>
$foo = 'foo_value'
class a {
$bar = 'bar_value'
include b
}
class b inherits c {
notify { $baz: } # should not generate a warning -- inherited from class c
notify { $bar: } # should generate a warning -- uses dynamic scoping
notify { $foo: } # should not generate a warning -- comes from top scope
}
class c {
$baz = 'baz_value'
}
include a
</pre>
This should produce three notify messages: "foo_value", "bar_value", and
"baz_value". Only the notify statement for $bar should produce a deprecation
warning.

Feature #5027: Issue warnings when using dynamic scope

This ticket captures a decision made on the developer mailing list on Oct 12
(see email thread "Questions about variable scope").
In Puppet version 2.7, a deprecation warning should be issued whenever a
variable reference takes place or a resource default is applied as a result of
dynamic scoping.
Dynamic scoping means that variables and resource defaults defined in class A
also take effect in classes that A includes. The warning should advise users
that this feature will be removed in a future version of Puppet, so they should
start using other puppet features (such as parameterized classes) to achieve
the desired effect.
