What I usually do in that case (in my own code) is to write a
function accepting exactly one (required) item, and use the '/' or '!'
operator before if it can be empty:
let $val as item()? := f()
return
$val ! g(.)
But this is more a cosmetic question I would say (meaning: different
people have different taste, and there is no "more valid" taste), and
consistency is the key here (across all functions in the same module).
