This is total bollocks unless you can optimize away the additional
temporary and the copy-in&copy-out operations. I don't see _that_
happening any time soon.

Plus, there is much more detailed information readily available in the
front end than what the middle-end will be able to derive.

So it's only right to add these transformations in the Fortran front end.
