yml RangeError: Maximum call stack size exceeded

[wouterkroes]

When having invalid yml I get a RangeError: Maximum call stack size exceeded

Example of this invalid yml file:

title: testing
description: description details
demo: | {}
implementation: implementation details

Would be nice if we could make this documentation system more flexible anyway. For instance the implementation field should be able to have a bit more body than just one string without special characters.
