Title: Report problems with invalid use of ROW(dataset)

- The argument to ROW(dataset) didn't check the dataset really was
active.
- Without catching this error you may get strange internal errors which
are hard to debug.
- The alias check could fail with some unusual user code using
undocumented features.
