Great! Thanks for trying it out and giving some feedback

Yes. The data bindings will construct the fully qualified name of the
variable (so class pt3 ($var) {} looks up pt3::var) in order to make
sure that they are kept unique.

This is because of the name of the variables that are looked up. The
puppet backend will try to lookup pt3::data the variable named
pt3::var. This is a known limitation and the data bindings were not
meant to support the puppet backend.

output below indicates that it still does.
