DTIO, DTP, and Submodules

[Paul Richard Thomas]

Dear Damian,

I have contemplated how to implement parameterized derived types and
inquiry functions on more than one occasion. We have developed most of
the machinery that is required in the process of implementing classes
and finalization.

However, all of my effort on gfortran right now is devoted to the
reform of array descriptors for which PR56818 is the meta-bug. See
https://gcc.gnu.org/wiki/ArrayDescriptorUpdate. Tobias is providing a
lot of help on this work. When completed this will make gfortran, at
last, fully F95 compliant! (array pointers to components of arrays of
derived types do not work preperly.).

With best regards

Paul

In case it helps at all to have a user perspective, I would have immediate use for DTIO and submodules.  I’ll probably use derived type parameters eventually, but might hold off on using derived type parameters in hopes that someday the language will have a more complete generic programming capability.
