But the IBM chap who posted a note about this pointed out that ISUB
in fact _transposes_ the array. That's expensive in both time and
space. In Ada, because the storage mapping is unspecified in the LRM,
an implementer can choose to go column-major if his target audience
is doing a bunch of Fortran interfacing.
Indeed, an implementation-dependent pragma could be used to let the
programmer inform the compiler that certain array types were to look
"Fortran-ish". This would all be perfectly legal, and - unless I am
missing something really fundamental - not terribly hard to implement.
Unhappily, no Ada implementer took advantage of this opportunity to
make Ada more Fortran-friendly. Happily, Ada 95 standardizes the
whole thing with Interfaces.Fortran.
