C++'s cast operators are be useful here --- for example, const_cast lets 
you cast a variable from const foo* to a foo* without inadvertently 
casting a foo* to a bar* if the type of the variable changes to const bar*.

The GDB people are slowly migrating their C-style codebase to C++, and 
without turning it into a a GoF book appendix. Maybe we can do the same 
someday.
