Actually this is valid and should be equivalent to { this: ~, is not: ~, yaml: ~ }.

You are right. But this string wasn't even parsed before, was it? But we should nonetheless choose a better failing test case here.

Honestly i have no idea if it worked, this part of the code is really hard to understand and i'm certain it leads to unexpected behaviors (by reading it, i think { foo bar } results to { foo: bar }).
I don't think this is the right fix even if it would prevent some unexpected behaviors, this part of the code has to be rewritten to be clearer and more testable.
