YAML is really quite complex. I like it in general but it's impossible to dump the data out without destroying the structure of the file (throw away comments, change whitespace, formatting style etc.)

Did you look at https://pypi.python.org/pypi/ruamel.yaml ?

Nope. Did not see it. That's neat though. Would probably have done it differently in that case, but no real reason to switch now.

TOML? It was made because YAML was too complex.
