Yes, we only have function-lookup() which uses the function name and
arity -- not the exact signature. And anyway, it is to be used in
"pull style" not in "push style".

I gather that function-lookup() cannot be used for maps, although a
map is a function. Is this right?

Or probably there are new things coming in XPath 3.1?
