Puppet users - Nov 2014 - Variable interpolation failing with structured facts

Hi,

While implementing custom facts in our environment I did some 
experimenting with structured
facts in our Puppet manifests. Puppet is 3.7.2, Facter is 2.3.0, Master 
and Agent run on the
same VM, future parser is on and stringify_facts is disabled.

I failed at using one of my custom facts (an array of hashes) in Puppet 
manifests,
so I did some tests with the "os" core fact and failed as well.

To debug my manifest I added these two notice() calls

notice($os[family])
notice("$os[family]")

and observed this output:

: (Scope(Class[Dummy])) RedHat
: (Scope(Class[Dummy])) {family => RedHat, name => CentOS, release => 
{major => 6, minor => 5, full => 6.5}}[family]

This is kinda weird, it seems as if Puppet fails to interpolate 
structured facts in double-quoted strings,
because both calls to notice() should output the same text, right?
Or did I miss something?

Cheers,
Tom.
