You cannot by any means access parameters of declared resources from
outside those resources, regardless of the mechanism by which those
resources are declared.
You can, however, access *class variables* from anywhere, provided that the
class has been declared. Simply use the variable's fully-qualified name,
such as $parent::version.

That statement appears to come from this doc:
http://docs.puppetlabs.com/puppet/3/reference/lang_scope.html. I suggest
you read the whole thing, but the bottom line for this case is that the
only child scopes of class body local scopes are the bodies of other
classes that inherit from it.
