ClosurePtr<> - Evil version 

For compilers where data pointers are at least as big as code pointers, it is possible to store the function pointer in the this pointer, using another horrible_cast. Invocation isn't any faster, but it saves 4 bytes, and speeds up comparison and assignment. If C++ provided direct language support for delegates, they would produce asm code that was almost identical to this. Note that the Sun C++ and MSVC documentation explicitly state that they support static_cast between void * and function pointers.
