What are the advantages and disadvantages of using boost::iterator_facade?

Yep -- the title pretty much sums it up. I've got quite a few types that implement iterator concepts, and I'm wondering if it's worthwhile to pull in this boost header instead of implementing things manually.

So far:

Advantages

Well specified
Less likely to have bugs

+2 A:

If maintaining your own iterator types becomes a burden then switch to boost. They are well specified and tested and less likely to have bugs.

Okay.. +1 ... but how? The facade is just a frontend that defines the required operators for you on the iterator.

Can you post one of your iterators with the question how do I do this with boost?

@epronk: Sure, there's an example using `iterator_facade` in my other question: http://stackoverflow.com/questions/2590310/can-i-use-boostmake-shared-with-a-private-constructor

So, what is remaining of the 'how' part of your question?

@epronk: I was asking how `iterator_facade` would reduce the incidence of bugs. At this point I don't think it matters all that much. Here, have +15 rep :)
