Hi,
this is not an ordering issue.
Perhaps not.
$foo = 'Class["a"]'
The above string is not blessed into a class reference when used as the
value for an ensure parameter (apparently). Not quoting it makes no
difference.
Are you sure that quoting vs. not quoting doesn't make a difference? At
least with the future parser, the unquoted version ought to be a bona
fide class reference in any context, and I didn't think that was new.
Or are you suggesting that the reference gets stringified upon
assignment to a variable? I've never done much along these lines, but
that sounds surprising and a bit inconsistent to me.
The 3x catalog/resource API requires that type references are indeed
stringified. Internally that string is then turned into a Resource
instance where only type and title are filled in.
So, yeah, atm, there is no difference between a quoted reference and a
real resource type reference. There will be when we in a later version
of puppet improve the catalog and compiler (although the string type
will most likely still be supported, it will be more efficient to use a
type).
