As someone involved in the packaging side of this, I think while we'd eventually /appreciate/ a TOML parser in the standard library, I agree with Victor that there's no rush, for two reasons:
1. setuptools and pip have a decent number of dependencies that we vendor /anyway/, so vendoring one more is not a big deal. 2. We will be supporting older versions of Python for some time to come, so we'd need to vendor a TOML-parser backport for several years before we could actually use the one in the standard library. I think /if/ a 1.0 version of the spec is going to be forthcoming (not clear from the issue requesting it: https://github.com/toml-lang/toml/issues/515 ), then it's worth waiting at least a bit longer for it. I also think it's probably worth asking the current maintainers of TOML-parsing libraries if /they/ think it's time to adopt/adapt one of their libraries for use in the standard library. They probably have a better perspective on the stability and maturity of their codebases.
