Puppet

I just finished a parser modification that allows to append stuff to defined variables in sub-scope (it still meet the puppet requirement that variables are write-once).

Here is an usage example: $ssh_users = [ ‘myself’, ‘someone’ ] … class test { $ssh_users += [‘someone_else’] … }

In the test class, the $ssh_users array is [‘myself’,‘someone’,‘someone_else’].

Please review and merge if it meets the necessary requirements.

The patch consists in 2 commits based on 0.24.x which are hosted in the feature/append-var branch in the masterzen/puppet github repository, or directly from: http://github.com/masterzen/puppet/tree/feature%2Fappend-var
