I love how you can wrap the C++ casts behind macros, and then
take advantage of them in code that compiles as C or C++:

  #ifdef __cplusplus
  #define strip_qual(TYPE, EXPR) (const_cast<TYPE>(EXPR))
  #define convert(TYPE, EXPR) (static_cast<TYPE>(EXPR))
  #define coerce(TYPE, EXPR) (reinterpret_cast<TYPE>(EXPR))
  #else
  #define strip_qual(TYPE, EXPR) ((TYPE) (EXPR))
  #define convert(TYPE, EXPR) ((TYPE) (EXPR))
  #define coerce(TYPE, EXPR) ((TYPE) (EXPR))
  #endif

The GNU C++ compiler has a -Wold-style-cast warning option to find
places in your code where you're neglecting to use these macros.

Compile the code as C++, and the macros will catch issues, like some
change in the code that suddenly causes a convert(X, Y) call to suddenly
be stripping away a qualifier.
