I'm a little confused. You expected anything else in an f95 compiler? 
This is part of what is arguably the biggest and most complicated new 
feature in f2003. While I'd love to see it supported, that's because 
I'd love to see an f2003 compiler. By the time you have that stuff 
done, you would be most of the way to having an f2003 compiler and 
could, with some justification, start referring to it as an f2003 
compiler that wasn't yet feature complete, rather than an f95 compiler 
with a few f2003 features.

Sort of like an f77 compiler that added on f90 modules. There basically 
never were any of those because modules were so big that by the time 
you had them done, you might as well finish f90.

Type extension isn't quite that extreme because you actually can do 
type extension without adding in the rest of the object-oriented stuff. 
The latest release of the NAG compiler does that. But I also noticed, 
in testing out the NAG compiler, that it doesn't actually do much good 
to have type extension without some of the other object-oriented 
features. I could define some extended types, but it turned out that 
whenever I wanted to actually do anything useful with them, I quickly 
ran into needing other of the f2003 features (that NAG hadn't yet 
done).
