This module subclasses Class::Accessor in order to provide lvalue
accessor makers.

.IX Header "CAVEATS"
.IP "\(bu" 4
Though Class::Accessor mutators allows for the setting of multiple
values to an attribute, the mutators that this module creates handle
single scalar values only.  This should not be too much of a
hinderance as you can still explictly use an anonymous array.
.IP "\(bu" 4
Due to the hoops we have to jump through to preserve the
Class::Accessor \->get and \->set behaviour this module is potentially
slow.  Should you not need the flexibility granted by the \->get and
\&\->set methods, it's highly reccomended that you use
Class::Accessor::Lvalue::Fast which is simpler and much faster.
