Is it possile to create yaml object from helm from file

Question

I want to iterate over the Yaml list which is defined in the file, and use it in Job. For example i have

test.yaml

    list:
      - first element
      - second element

In _helpers.tpl i can define 
something like 

{{- define "mychart.list" -}}
{{ .Files.Get "test.yaml"| toYaml }}
{{- end }}

And then in Job i want do something like 

    {{- $lists  := include "mychart.list" . }}
    {{- range $element := $lists.list}}
    apiVersion: batch/v1
    kind: Job
    metadata:


and then use the $element.

But when i am trying to do the dry-run with --debug it complains about 

at <$lists.list>: can't evaluate field list in type string.

Looks like whole value is coming as string rather than Yaml, does it needs explicit call to Yaml parser ? If yes, is there a way to do that ?

BTW i have also tried various combinations of 

    {{- $lists  := include "mychart.list" . | toYaml }}

or loading the file inline, but none of them helps.

I can put the list in Values.yaml, but don't want to do that purposely.

Any help is really appreciated.

Just putting for future reference, if someone comes and have look.

There's fromYaml function, which is undocumented. I found it hard way, but that solved the isssue.

{{- $lists := include "mychart.list" . | fromYaml}}
