You don't have to go that far to have great callback support. C# (and
Delphi) show a great model that I wish C++ had adopted from the
beginning. C++ could have declared that a function pointer contains the
function pointer plus the (optional) this pointer. That would have dealt
with the whole (important) issue.

Well, C++11 brings in the lambda (<URL:
http://www.cprogramming.com/c++11/c++11-lambda-closures.html>):

   One of the biggest beneficiaries of lambda functions are, no doubt,
   power users of the standard template library algorithms package.
   Previously, using algorithms like for_each was an exercise in
   contortions.


Using void pointers in C++ is like sacrificing to the idols.
