I think it okay:

      procedure ::foo => afoo, bfoo

is equivalent to:

      procedure :: foo => afoo
      procedure :: bfoo => bfoo


>From Fortran 2008:

R448   type-bound-procedure-stmt
   is  PROCEDURE [ [ , binding-attr -list ] :: ] type-bound-proc-decl-list

R449  type-bound-proc-decl  is  binding-name [ => procedure-name ]

C464 (R448)  If => procedure-name appears in a type-bound-proc-decl, the
double-colon separator shall appear.

If neither => procedure-name nor interface-name appears in a
type-bound-proc-decl, it is as though => procedure-name had appeared with a
procedure name the same as the binding name.



Note: Fortran 2003 didn't allow a list, i.e. with -std=f2003 it is correctly
rejected.

Fortran 2003:

R451  specific-binding
   is PROCEDURE [ (interface-name) ] [ [ , binding-attr -list ] :: ]
                binding-name [ => procedure-name ]
