Trevor,
Can you perhaps attach a manifest that I can run "apply" on to illustrate the
problems you're describing? I've attached one that I was playing with to try
to come up with a repro case, and I when I attempt to apply it I get this error:
Could not parse for environment production: Cannot assign to variables in
other namespaces at /my/path/13323.pp:7 on node cosmicshame.puppetlabs.lan
I get similar errors if I try to copy and paste from the code snippets that
you've provided here, and I want to make sure that we understand exactly where
the scoping issues are impacting you before attempting to diagnose further.
Thanks!

Bug #13323: Issues with variable scoping.
https://projects.puppetlabs.com/issues/13323#change-58740
Author: Trevor Vaughan
Status: Needs More Information
Priority: Normal
Assignee: Trevor Vaughan
Category:
Target version:
Affected Puppet version: 2.7.12
Keywords: ambiguity, variable, scope
Branch:
According to http://docs.puppetlabs.com/guides/scope_and_puppet.html, we should
be attempting to use fully qualified variable scoping across the board.
However, I've run into a situation where there appear to be some serious issues.
Example:
class foo ($var1 = 'something') {}
class foo::baz {
if $foo::var1 == 'something' { do something }
}
class bar {
$foo::var1 <- does not exist because it looks in bar::foo
class { '::foo': var1 => 'baz' }
}
class bar::foo { stuff... }
The issue is that $::foo::var1 is NOT the same as $foo::var1 though both can be
successfully declared anywhere across the manifest space. This causes very
non-deterministic actions when using both variants though they should both
really be the same thing.
So, what is correct? Should we always use $::variable::thing or is the code
incorrect and they should both be valid at the top scope when there is no lower
scope overriding that variable?
