Possibly these can all be done - but just require more work. The ones that I 
have done have an existing Qt ctor that does the unpickling (although I 
invented a new one for QDateTime). Many of the above are actually unions of 
different data structures and it may nor always be possible to extract the 
data in the correct form.
