I cannot find an explicit prohibition, either, but please consider these
related statements from F2003:

    Section 12.3.1: ..."The interface of a statement function is always

    Section ..."A procedure other than a statement function shall
have an explicit interface if it is referenced and a reference to the procedure
appears with an argument keyword"

That still leaves the prohibition unstated. However, I find the following in
the Fortran 2003 Handbook (Adams et al), p. 451:

14. A statement function is referenced in the same manner as any other
function, except that because statement function interfaces are implicit, the
keyword form of actual arguments is not allowed; the argument association rules
are the same.
