It is a bug that is planned to be fixed in Puppet 4. (It cannot be
changed in the 3.x series as it would potentially be a breaking change).
Yes, we are serious about semver :-)
The future parser (and hence also in Puppet 4) allows concatenation of
array (and merge of hash) to a *new* variable otherwise variables are
strictly immutable.

Hi!
Is it possible to add a new element to an array inside puppet
manifest ? Something like ruby's array.push('new_element') ?
No, it isn't. It is a fundamental principle of Puppet that
variables' values cannot be changed once set..
In particular, the += operator Daniele refers to does not do quite
what she supposes: it sets the initial value of a local variable by
appending data to the value of a /separate/ variable of the same
name at top scope, node scope, or a parent scope
(http://docs.puppetlabs.com/puppet/3/reference/lang_variables.html#appending-assignment).
That may be sufficient for your needs, but it is not what you
actually asked, and I would not expect the code Daniele presented to
work.
