This can be simplified to just

'1':
  'include': '#types'

It stops working when i do that

I see the thing you're trying to solve, but I think it could be solved in a much cleaner way...

You should have a look at how this is solved with multiline variable declarations which are essentially the same thing, but then for variables instead of types.

Especially have a look at the use of 'include': '$self' which helps to prevent duplication code.

@svanharmelen - I looked at the variable declaration section, im not sure i understand how the $self syntax is helpful for what i'm trying to achieve here

@svanharmelen is there a path forward on this PR?

@joefitzgerald I'm sorry, but I have to admit that I switched back to vim about 10 months ago. So I don't think I'm still the right person to judge this PR...
