Singleton array

[stevedwray]

I was developing some Puppet code to create YAML for bind resource records (using Inkblots bind module) out of existing Hiera data (for server network interfaces) when I came across this in my test code:

yaml_setting {
"host1_rrdata":
   target => "/tmp/yaml_setting.yaml",
   key => "dns_rrs/host1/rrdata",
   value => [ "10.0.0.1" ];
 }

results in
dns_rrs:
host1:
rrdata: "10.0.0.1"

rather than the expected
dns_rrs:
host1:
rrdata:
- "10.0.0.1"

specifying type => 'array' made it generate a YAML array but I think giving it an array, even with one element, should have worked.

If I gave it an array with multiple entries in the Puppet code it worked fine.
