Note: When converting void* to T* you can use use static_cast, which is well-defined. For example

    int* x = static_cast<int*>(malloc(sizeof(int)));

BTW, I find this useful when programming in a C dialect that compiles as 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

Very cool; you just use these macros for all your casts, and when building using a C++ compiler, you get additional diagnostics, like that you're accidentally stripping away a const-qualifier.

You just re-invented MFC macros for the C++ features that were being discussed for ISO C++89.
