Yes, that's right. That is, it's fine to have this:
{
char const *p = &a[i];
...
}
because the 'const' is talking about p's value, not about p itself, and
the value's const-ness is often non-obvious. In constrast, it's dubious
to have this:
{
char *const p = &a[i];
...
}
because this 'const' is talking about p itself, and p is a local
variable so it is typically obvious (by inspecting the "...") whether p
varies.

Yay! Thanks.
