FIXME - Remove the following compatibility notes after a handler
class for vec_t is implemented.
To preserve compatibility with the existing API, some functions
that manipulate vector elements implement two overloads: one taking
a pointer to the element and others that take a pointer to a
pointer to the element.
This used to be implemented with three different families of macros
and structures: structure objects, scalar objects and of pointers.
Both the structure object and pointer variants passed pointers to
objects around -- in the former case the pointers were stored into
the vector and in the latter case the pointers were dereferenced and
the objects copied into the vector. The scalar object variant was
suitable for int-like objects, and the vector elements were returned
by value.
There are both 'index' and 'iterate' accessors. The index accessor
is implemented by operator[]. The iterator returns a boolean
iteration condition and updates the iteration variable passed by
