Docs incorrect (or found bug?) about Front Matter in Pug layouts

[Zearin]

Relevant Docs

The docs for Layouts say:

Layouts can contain their own front matter data!

The problem

I’m using Pug as my template language of choice, and I just tried to add some Front Matter to a layout for the first time. Pug sees the front matter code and chokes when attempting to parse it.

Error output

My speculation

Since each parser only knows its own language (but not front matter), my guess is that Eleventy is sending the entire file contents to the Pug parser, when it should be pre-processing the front matter first and sending only Pug code to the Pug parser.
