Research direction

Start with the [.data.table entry point and the error message referenced in the issue, then review bug #1593 and the linked R-Forge report for the intended two-column matrix behavior. Reproduce the current result for matrices with equal and differing column types, and add coverage showing that the result is a vector when types match and otherwise a list.
