Puppet users - Jun 2009 - Referring to a class variable using its name as a string value

It would be great if I was able to refer to a variable in a class namespace
using only it''s string value.

I guess this is a kind of eval-esque construct for those familiar with Perl
and Python.

Example source :-

^^^^^^^^^^^^^^^^^^^^^^^^^^^

$classname = ''foo''

class foo {
    $bar = "baz"
    notice("I am class $classname with a variable \$bar=$bar")
}

include $classname    #   Awesome - I can use a string value for class
includes!
notice("$foo::bar")    #    I can reference a value using its *actual*
name
...

#   But this doesn''t work ...

$value = inline_template("$<%= classname %>::bar")

notice("I''d really like ''baz'' below but I only
get \$foo::bar")
notice("$value")

^^^^^^^^^^^^^^^^^^^^^^^^^^^

output :-

notice: Scope(Class[foo]): I am class foo with a variable $bar=baz
notice: Scope(Class[main]): baz
notice: Scope(Class[main]): I''d really like ''baz''
below but I only get
$foo::bar
notice: Scope(Class[main]): $foo::bar

So near and yet so far :-(

Is there a way to do this using some special syntax, a function call or a
possible plugin perhaps?
