Some practical application of where blocks might be used would be really useful. Though by no great stretch of the imagination I can easily think of some myself just from reading your article. Thanks very much. I agree with Matt. Some practical application of where blocks might be used would be really useful.

I understand the concept but can't immediately see why I would want to do it (poor imagination on my part perhaps.) matt Hi,

It might be useful to include a ‘real world’ example of how this sort of thing can be used. I understand the concept but can’t immediately see why I would want to do it (poor imagination on my part perhaps.)

It isn't possible to customize the logic executed per iteration using STL iterators alone. You have to combine iterators with functors to get closure/block behavior. (And, in C#, anonymous delegates do the job). Actually functors are the C/C++ equivalent and not iterators. It isn’t possible to customize the logic executed per iteration using STL iterators alone.

I now actually understand how to make methods that use blocks. However, damn you at the same time. I have started rewriting my methods now to take advantage of this new found knowledge :) Seriously though, thanks. Hey, fantastic job. I now actually understand how to make methods that use blocks.
