Thanks a lot for the nice sample!

One more question:

# converting the elements to JSON pointer paths
my @elements = map {s!\.!/!gr} (qw/ userName displayName meta.created 
+/);
[download]

qw does not support interpolation right? So I can't use a string there too :-(
Is there a way around to dynamically change the values there?
Background: The values are coming from a config-file. So if I add a new entry like "meta.user" in the config, it should work without touching the code...
