Config levels

This is possible with the prefix of a tab, indicating that its in the last key given, for example:

my_key
    other_key other_value
    final_key final_value

Would be valid but

my_key my_value
    key_ wouldnt val_work

Wouldn't to work better with HashMap and interop with json and others.

If you're interested, you could take a look at a library I built which abstracts away "Block-parsing": indented-blocks. Documentation is not that good, but it is probably mostly self-explaining. Entry methods are parse_nested_blocks and the Block type.
