test: Simple In Place Substitution
brief: >
If you want to reuse an entire alias, only overwriting what is different
you can use a << in place substitution. This is not part of the official
YAML spec, but a widely implemented extension. See the following URL for
details: http://yaml.org/type/merge.html
