The NumPy and SciPy developers who are implementing support for PEP 465
('@' as a dedicated matrix multiplication operator) will likely want to
test against a development version of 3.5 at some point. Using 3.5 isn't
strictly required, though, since supporting the @ operator is mostly a
matter of implementing the new __matmul__ methods and one can test those
by calling them directly instead of using the new operator.
