this is what you want (Score:1)
You are interested in the value of the "optional_features" key, and you expect that to be a ref to a list of two elements: the first element is "foo"; the second is a ref to a hash of the other data.
When you describe what you want you can see that the list has 2 elements. So in YAML you need one "-" for each element. So what you want is:
optional_features:
- foo
- description: test
requires_os: Linux
requires:
Test::More: 0.47

Except it isn't ;)
optional_features is a list, with each element of the list being a map with an identifier. The indentation I'd used made it look like the list element had no identifier, hence why 'foo => undef' existed inside the map, when I meant for it be the identifier for the map. ferreira [perl.org] has put me on the right track.
As I suspected, I had just misunderstood the specs, as I didn't think I could have been the first person to come across this.
As for indenting in use.perl, you want '<ecode>'

You say "each element of the list being a map with an identifier". That is possible in Perl6, but in Perl5 a list (or array) element can only be a simple scalar or a reference to something.
So I think you must mean that you want a list that looks something like this: [ foo => {
Is that what you want?
That list has 2 elements: the first is "foo"; the second is a hashref.
In your initial post you sai
