lvalue methods are a questionable idea, at least if used universally.
an lvalue method just exposes a variable (ie the storage for) to the assignment, it runs b4 the assignment is done.
It gets no chance to validate the RHS, thus you could accidentally do:
$person->age = -1;
$person->name = '2/22/01';
$person->ssn = 'capt. bob'; Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
