Thanks all, it works. Is this documented or have you figured this out
by trial and error? I'm not trying to blame the docs, it's just that I
couldn't find anything about the ${} rule.
Apparently there seem to be more differences between classes and
defines wrt. scope. When I use template("foo.erb") inside a define() I
don't have direct access to facts or other variables (fex. the $name).
However scope.lookupvar('name') works. Is this expected behaviour?
thanks again
Paul
