okay, this works.
test.pp
class a {
$inline = inline_template(
'<% scope.lookupvar("interfaces").split(",").each do |interface| %>
<% @int_ip = scope.lookupvar("ipaddress_" + interface) %>
<% @int_name = Resolv.new.getname @int_ip %>
<%= "#{@int_ip} :::::::: #{@int_name}" %>
<% end %>')
notify { $inline: }
}
include a
$ puppet apply test.pp
