Added ``kw_only`` arguments to ``attr.ib`` and ``attr.s```, and a corresponding ``kw_only`` attribute to ``attr.Attribute``.
This change makes it possible to have a generated ``__init__`` with keyword-only arguments on Python 3, relaxing the required ordering of default and non-default valued attributes.

Expand examples with `attr.s` level kw_only. * Add `kw_only` to type stubs. * Update changelog for rebased PR. Hear ye, hear ye. A duplicate PR is born. * Tidy docs from review. * Tidy code from review. * Add explicit tests of PY2 kw_only SyntaxError behavior. * Add `PythonToOldError`, raise for kw_only on PY2. * `Attribute._evolve` to `Attribute._assoc`. 2018-08-11 04:40:01 +00:00			Added ``kw_only`` arguments to ``attr.ib`` and ``attr.s```, and a corresponding ``kw_only`` attribute to ``attr.Attribute``.
