Re: Pandas new version

Control: tags -1 fixed-upstream patch

The test failure is that np.array @ pd.DataFrame (matrix product) tries 
to keep both the DataFrame's indices, which fails because the new matrix 
is a different shape.

This appears to be fixed in 0.24.1 from PyPI, but as previously noted, 
this is a new major version and hence risks breaking rdeps.

The relevant change appears to be setting __array_priority__:

but I haven't actually tried applying only that to 0.23.
