[xquery-talk] From map entry pairs to a pair of arrays

Fact of the matter is that if a low level optimization can be made, it must

depends on the use case.

Don't assume that other languages are inevitably more efficient than XQuery.

And don't assume that the cost of moving/converting data from one
