To include anchors, a literal including and parsing are needed. But the constructor would parse the including parts first.

For such a thing, a template engine like Jinja2 may be useful.
We shall render all YAML data into a whole one, then parse it.

eg:

• bar1.yml:

  bar1: *boo
    k1: "1.1"
    k2: "1.2"

• bar2.yml

  bar2: *boo
    k1: "2.1"
    k2: "2.2"

from textwrap import dedent
import jinja2
import yaml

env = jinja2.Environment(loader=jinja2.FileSystemLoader("search path"))

tpl = env.from_string(dedent('''
boo: &boo
  k1: "0.1"
  k2: "0.2"

bars:
  {% include bar1.yml %}
  {% include bar2.yml %}
''').strip())

s = tpl.render()
yaml.load(s)

However, above code can NOT work properly, because of indention problem.
