That's what I understand the standard.  But I was thinking about a 
procedure like:

SUBROUTINE final_vector(v)
  IMPLICIT NONE
  TYPE(mytype) :: v(42)
END SUBROUTINE final_vector

Could this be called for a vector of dimension, say, 100 in regular 
code?  I just assume not.  But the standard is suggesting (only matching 
rank) it should be called to finalize a vector

TYPE(mytype) :: vector(100)

which is what I mean.  So I thought about warnings for defining a 
procedure with explicitelly shaped arguments FINAL (but for those 
without ELEMENTAL/matching rank procedures I like the idea, too).
