I thought of that ... it was tempting, but being extra rigorous w/my stuff, I wanted the values inspected through direct inspection
$p->{one} to be consistent with the ones done through the accessor
$p->one.
FWIW, in my case, I don't need to check the value before the assignment, but immediately
AFTER the assignment. For example -- wanted to be able to have a URL object where I break
it down into proto,site[:port]/path, then, if I assign to $p->path,
it would automatically be reflected in $p->url.
