R: Getting whisker to loop over a list with unknown names

I'm trying to use Whisker for HTML-templating in R, but seem to run into problems that should be an easy task for the package. All I want to do is to use sections to loop over a list, with the only problem that I cannot know and therefore specify the names of its elements:

library(whisker)

hash <- list(
  people = list(
    a = list(
      first = "john",
      last = "johnsson"
    ),
    b = list(
      first = "peter",
      last = "petersson"
    ),
    c = list(
      first = "steve",
      last = "stevesson"
    )
  ),
  stuff = c(1:5)
)

template <- "
{{#people}}
<h1>Hello {{first}}</h1>
{{/people}}
"

result <- whisker::whisker.render(template = template, data = hash)
print(HTML(result))

Expected output:

<h1>Hello john</h1>
<h1>Hello peter</h1>
<h1>Hello steve</h1>

I tried using {{#.}} and . in all possible constellations, but no luck. This should be a basic requirement of a templating package and I refuse to believe that it isn't possible :S

Any good alternatives to whisker in that case? Thanks
