Yes, I think it's best to stay close to the C++ grammar in that respect: 
The above contains a single (toplevel) declaration, with 4 (toplevel) 
declarators. There already is a VarDecl cursor for 'p2', whose extent is 
just the 'p2' token itself. The declaration this is part of then is the 
same for all four declarators, with the same extent, from 'static' to ';'.

Thanks,
