Description

In https://saxonica.plan.io/boards/5/topics/6712 Martin Honnen discovered cities/city!(@country || ', ' || @name) produced a mixture of nodes and strings.

Investigation shows that the dynamic compilation of the || operator merely creates a concat() call around the (compiled) arguments, with no type checking/coercion. (A specific concat() function call does carry out type checking.)
