Due to the dynamic scoping of them I only really use them for setting
global defaults. And some mechanism for doing that is really needed.
I've used to do that to set file buckets and Exec#path. But importing
modules really put a stop to that as I saw that I didn't really need that:

Using them inside classes is really mostly syntactic sugar to get the
code shorter. But I've also seen them used to conditionally set an
attribute. So not set it to value or undef, to set it to value or not
set it at all, as that has slightly different semantics. But that would
also really be better to do with some sort of postfix if condition in
the resource declaration.
Like this:
file { "/foo": ;}
if $x { File["/foo"] { source => $x } }
?
See
https://github.com/DavidS/dasz-configuration/blob/master/modules/hosting/manifests/customer_service.pp#L17
for a more elaborate example.
