Expected output:

Hello 1!
Hello 2!
Hello 3!

ps. Mustache v1.1.0 behaves in the same way.

(Might be unrelated:)

I'm not sure what this line is supposed to do (what are we "merging" and why?):

mustache/bin/mustache

Line 89 in 7b22ed0

puts Mustache.render template, yaml.compact.reduce(&:merge)

but it certainly makes no sense to me.
Replace

        puts Mustache.render template, yaml.compact.reduce(&:merge)

with

	yaml.compact.each { |item| 
	        puts Mustache.render template, item
	}

and it works as expected.

Is this project even active? This issue was reported > half year ago with a trivial fix. Got bitten by it recently. :(
