The patch set looks okay. I am not 100% sure how compatible your changes 
are with regards to finalization and coarray components, but I have the 
impression they don't make thinks worse.

Regarding the comment:
  "A data-pointer-returning function should be considered as a variable 
too."

That's actually true according to the standard, which since F2008 allows:
  f() = 7
where f() returns a pointer. Well, gfortran doesn't support this yet and 
there are also some issues if the LHS is an operator expression (see 
current interpretation request discussions), but I thought I mention it 
for completeness.

Thanks for the patch! - And for the thorough patch reviews!
