Hi,
In case you are interested in what is happening on the bleeding edge of
Puppet development, I have started with a series of blog posts about the
new Type System that will be released in Puppet 4 and is available as an
experimental feature in the experimental --future parser released in
Puppet 3.5.
The series (there are six posts) about the type system starts
here:
