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.
