Merge key (yaml 1.1) operator "<<" treated as normal key

[kosiu]

According to yaml 1.1 operator "<<" is used to merge keys pls see:
https://yaml.org/type/merge.html

for input:

<<: {A: 1, B: 2}
A: 0

should be:

{ "A": 0, "B": 2 }

and it is:

{"<<": {"A": 0, "B": 2}, "A": 0 }

I'm not sure is it fortran-yaml-c or underlying c library.

Ok, it's not part of the standard
yaml/libyaml#168

Ok, so we have to wait until libyaml is fixed.
