This is the "Norway Problem".  A YAML block like this:

    geoblock_regions:
      - dk
      - fi
      - is
      - no
      - se

evaluates to the equivalent JSON:

    {"geoblock_regions": ["dk", "fi", "is", false, "se"]}

Example taken from this page, which has many more examples where
semantic highlighting of YAML would avoid a LOT of footguns:
