In principle, the type of an empty array is immaterial. However, the type
becomes evident when an empty array is expanded with take or expand .

By RTM, in Sharp APL, when both arguments (of dyad ,) are empty, the result has
the type of the right argument. In I-APL the type of a cantenation of empty
arrays is the type of the leftmost array.
