The following commit has been merged in the squeeze-2.6.2 branch:
commit b7e4cbe5bc25ea669e3a6458390c255a1b34f61e
Author: Paul Berry <paul at puppetlabs.com>

(#4534/#4778) -- Normalize parameterized classes
This is a reconciliation/melding of Paul's
(#4534) Class inheritance with parameterized classes is no longer ignored
and Markus's
Fix for #4778 -- evaluate parameterized classes when they are instantiated
Extracted the code from Resource::Type#mk_plain_resource that evaluates
parents and tags the catalog, and moved that into a new method called
instantiate_resource. Instantiate_resource is now also called from
Parser::Ast::Resource#evaluate, so that the notation
"class { classname: }"
now executes this code too. Likewise adds class evaluation so that it behaves
the same (with regard to lazy / strict evaluation) as
include classname
