I might read Fortran 2003 wrongly, but I think alreay Fortran 2003
allows this
(cf. PR 29962):

Fortran 95, Section 7.1.6.1:
"(4) An elemental intrinsic function reference of type integer or
character where each argument is an initialization expression of type
integer or character"

Fortran 2003, Section 7.1.7:
"A reference to an elemental standard intrinsic function, where each
argument is an initialization expression"

Actually, I think Fortran 2003 allows to use matmul and dot_product,
which is currently unsupported by gfortran (-std=gnu).
