Daniel Chen wrote some text explaining why being able to uselessly extend a 
module was harmful.

Right, but Daniel suggested that not only was this useless, but also harmful to 
some extent.  Some might agree with that.

Which is precisely NOT what an interp is doing!

Once again, with feeling: I have no problem with disallowing this
   *** IN FORTRAN 2008 ***
via the defect resolution (interpretation) process, if that is what the rest of 
the committee(s) agree.

I am absolutely not suggesting we leave it permitted in F2008 but taking it out 
of F2015.  That would be irrational and unacceptable.
