In my case I triggered the error by attempting to instantiate a `DataArray` passing a nested tuple `coords=[('dim1', (point1, point2, point3)),...]`. Since I consider `tuple(list())` to be an anti-pattern I started looking elsewhere for the source of the error. Making explicit the use of tuple overloading would be helpful.
