If you use the Resource API (official docs:
https://puppet.com/docs/puppet/6.3/custom_resources.html, github:
https://github.com/puppetlabs/puppet-resource_api ), adding a canonical
internal representation is as easy as adding the `canonicalize` feature,
and define the required change on the provider:
def canonicalize(context, resources)
resources.each do |r|
r[:array_prop] = r[:array_prop].sort
end
end
The resource api also makes a lot of other pain of developing types and
providers go away, and supports all puppet versions from 4.7
