Well no, Puppet *is* interpolating. It is interpolating the string value
of the whole hash. What it is not doing is interpreting the index as an
index. Try this:
notice("${os[family]}")
I make it a general rule to *always* use braces around variable references
in quoted strings, even where not strictly necessary. It is harmless to do
so, and it saves having to determine on a case by case basis whether braces
are needed.
