Others have commented on usability aspects, and I agree entirely with what they say. As to performance, the Saxon implementation is probably optimized to support that usage pattern. In general, function calls in Saxon are more highly optimized than template calls. For example, Saxon-SA will move the body of a function inline in some circumstances, reducing the call overhead to zero and giving the opportunity for further optimizations.
