PUP-8084

Thanks for your answer. In fact, explicit lookup didn't work either.

The aim of having a regexp in "hiera yaml" was to generate a yaml file from that hash that need to get regexp as key (searchguard plugin configuration for elasticsearch)
To do that, I was using a function with a "hash.to_yaml"

Now in Hiera, I put a string like ''!ruby/regexp ^foo-\S*' , and I wrote to function to get a real regexp in my hash before converting it to a yaml file.

  def transform_regexpkeys_to_regexp(value)

    return value if not value.is_a?(Hash)

    hash = value.inject({}) { |memo,(k,v)|

         memo[k.start_with?('!ruby/regexp') ? Regexp.new(k.gsub(/!ruby\/regexp /,'')) : k] = transform_regexpkeys_to_regexp(v); memo

    return hash

end

And I got the same yaml output as with earlier Puppet version
Maybe I could write this function using Puppet Language only
