Note that we've left a similar operand precedence handling issue languishing for a long time over compatibility concerns: https://bugs.python.org/issue11477

In that case, NumPy is actually benefiting from the discrepancy with the documentation though, as the lower-than-expected precedence of sq_concat and sq_repeat is what allows NumPy arrays to always take precedence over builtin container types, even when the array is the right hand operand.
