The smoke-tutorials CI failure looks related.

cf https://github.com/data-apis/array-api-compat/pull/361 for a fix and https://github.com/data-apis/array-api-tests/pull/397 for a test. Would be helpful if you could test-drive gh-361 @mdhaber

Numpy seems to do it: ``` In [8]: np.ones(3) @ np.ones(3, dtype=complex) Out[8]: np.complex128(3+0j) ``` cross-ref https://discuss.pytorch.org/t/matmul-mixed-dtypes/216044 for a pytorch discourse question.

Strangely enough, - testing locally, `python==3.10.0` from `mamba install python==3.10` is broken, but `mamba install python==3.10.2` works. - on CI, it seems to install `python==3.10.19` via the `setup-python` action.

Let me ping @crusaderky for dask, @adityagoel4512 and @cbourjau for `ndonnx`: what's bad/difficult/inconvenient in the test suite?

> whether tests that use a data strategy can actually use `example`s I suspect the answer is negative---did not test it myself though, so am open to pleasant surprises :-)....

> - Hypothesis hurts when there is a failure on an exotic edge case, but the only way to push through is to xfail the whole function including all of...
