String literal works, but (seemingly) equivalent argument doesn't?

I’m having trouble figuring out why using a string literal works here:

    {{ range .content.Site.Pages }}
      {{ partial "mappers/item-mapper-entries.html" . }}
    {{ end }}

but using a variable with the same value doesn’t:

    {{ $partialName := delimit (slice "mappers/item-mapper-" .resourceType ".html") "" }}
    {{ range .content.Site.Pages }}
      {{ partial $partialName . }}
    {{ end }}

In the latter case I get the “template missing or incomplete” error. When I ask for just the value of partialName, it seems correct:

partial name is: {{ $partialName }}
// mappers/item-mapper-entries.html

Am I missing something frightfully obvious about the way the variables are closed over on a range?

It looks like Hugo’s partial is enforcing the rule laid out by Go’s text/template of only allowing static names. Variables in Go, even if they represent literals, don’t meet this test and an error is generated.

I was able to get it working by using {{ partial (printf "%s" $partialName) . }} instead.
