I wouldn't use it for for-loops either, but man, boost::bind is so handy when compiled with boost::function! I used to use function pointers and 'void *userData'. If I wanted to pass additional data to the function then I have to allocate a structure and not forgetting to free it later which resulted in a lot of boilerplate code.
