--- Comment #9 from Damian Rouson <damian at sourceryinstitute dot org> --- Oh boy. I'm guessing that's an indication that there won't be any movement on this anytime soon. It seems this is one of only two major features missing for full Fortran 2003 compliance -- the other being derived type parameters. One of the Fortran committee members recently suggested that derived type parameters be deprecated. I wonder if the same is true of derived type I/O. If the leading open-source Fortran compiler already supports some features of Fortran 2008 and Fortran 2015 but has major features of Fortran 2003 missing a decade after the publication of the standard, maybe that's a sign that the feature should be removed from the language. Thoughts?
