Index .Site.Data and <nil>

I’ve got a data/authors.yaml file with a few nested keys. When somewhere down the tree a key is missing, I get an annoying but not very surprising exception:

<index $.Site.Data "authors" $id "name">: error calling index: index of nil pointer

… if there is $id, but no "name" defined.

What surprises me, is that if I do the same with $.Site.Params, it doesn’t throw an exception, which is a desired behavior in this particular case.

Of course, I can wrap it in with, with, with.

Is there a more elegant way to achieve the same behavior as with $.Site.Params? Out of curiosity, is there any reason for this difference in behavior? In other words, is it a feature or a bug?

you can set a default value for missing parts
