In cases like this, I typically use data() instead of fortran_vec(),
though the results are the same.  But as you say, the important thing
is to declare the Array object const so that the const version of the
fortran_vec() method is used.  Note that currently there is only a
const version of the data() method, so using it means that the code
will only compile without warning if the Array object is actually
const.
