I don't use objects alot (but I'm working on it on the weekends) but your above statement
is totally absolutely true. It would've be lovely - even for object-challenged folk like
myself. The public and private attribute in fortran 90 (for entire modules, individual
variables, structure components and/or internal subprograms) is one of the best additions
to that language I reckon.

p.s. My weekend IDL object tinkerings have certainly improved my Fortran 90 coding
techniques - or at the very least how I approach problems in that domain - that's fer
sure. And I can write my "get_properties" methods to do whatever I like. :o)
