'fraid so. :) ITypes refer to "Implementation Types"; see the same-named section in S06. It is the equivalent of Tie and other Magics in Perl 5. VTypes refer to "Value Types", such as "Int". The relationship between IType and VType namespaces is not clear to me. My current hypothesis is that every VType has a corresponding, same-named IType, that acts as a container restricting the incoming STORE calls to valid VType, either by casting or throwing an exception where it is impossible to cast. I may be totally wrong here, though. Thanks, /Autrijus/
