panic: template: template:19:25: executing "template" at <.Env>: map has no entry for key "Env"

Using .Env within range produces the following error:

panic: template: template:19:25: executing "template" at <.Env>: map has no entry for key "Env"

Example:

{{ range (datasource "gomplate").foobar }}
{{ .Env.FOOBAR }}
{{ end }}

Ah. yep. This is because the meaning of . changes within range. Probably the simplest way to resolve this is by using getenv instead of .Env:

{{ range (datasource "gomplate").foobar }}
{{ getenv "FOOBAR" }}
{{ end }}

Yes, that's what I've done. But I would have liked the fail-feature in case a variable is not set :)

@estahn ah - well another option could be something like:

{{ $root := . }}
{{ range (datasource "gomplate").foobar }}
{{ $root.Env.FOOBAR }}
{{ end }}

Hope that helps!
