RELEASE_TYPE: minor
This release improves Hypothesis' handling of positional-only arguments, which are now allowed :func:`@st.composite <hypothesis.strategies.composite>` strategies.
On Python 3.8 and later, the first arguments to :func:`~hypothesis.strategies.builds`
and :func:`~hypothesis.extra.django.from_model` are now natively positional-only.
In cases which were already errors, the TypeError from incorrect usage will
therefore be raises immediately when the function is called, rather than when
the strategy object is used.
