I am puzzled about C894. Is the following code not standard conforming?
end subroutine sub
end module mod
It is certainly intended to be.
According to R504, R507, R508 the interface belongs to the
specification-part of the module.
In Fortran 2008 this constraint was not present.
In Fortran 2008 this constraint was worded differently:
C1210 (R1209) The IMPORT statement is allowed only in an interface-body that
is not a module procedure interface body.
Why is this introduced?
Because F2015 has extended the IMPORT statement, and now allows it to appear
in many places forbidden by F2008.
"C894 (R867) An IMPORT statement shall not appear in the specification-part
of a main-program, external subprogram, module, or block-data."
Perhaps this should be changed to say "scoping unit" instead of
"specification-part". Or an exception added ", except that it may appear in
