Not so... The above is an error. 'baz' is less-indented than 'bar' and is
not at the same level as 'foo'. There are only three valid ways 'baz' may be
indented (each meaning something else):

---
foo:
- bar:
baz: boom # Same indent as 'foo', so this is
          # key:value in map containing 'foo'
---
foo:
- bar:
  baz: boom # Same indent as 'bar', so this is
            # key:value in map containing 'bar'
---
foo:
- bar:
   baz: boom # More indented than 'bar', so this is
             # key:value in map that is value for the
             # 'bar' key.
...

All three are "what you would expect". In all three cases, the indentation
of 'bar' is taken to be "two spaces", even though one of them is physically
a '-' - hence my wording.

Have fun,
