Good talk.. I remember reviewing the slides from when you gave the talk originally at the accu conference. :)  The very last question has a very simple answer that you forgot about and sort of danced around.

To repeat the question:
q) Why not have both iterators and ranges?

The answer was given earlier in the talk.. a) Iterators are fundamentally unsafe.

btw.. the birds chirping throughout made me really want to go to boostcon. That it's set in such a wonderful location (Aspen) is a major selling point.

Later,
Brad

Cool. I'm having some trouble skipping to the parts I'm interested in, can anyone point me to a downloadable video?

This works for me:
wget 'http://blip.tv/file/get/Boostcon-BoostCon2009Keynote487.flv?referrer=boostcon.blip.tv&ext=.flv'

I didn't find a download link, but had to go through the sourcecode and had to deal with their JavaScript/AJAX/XML crap. Why?

Because you don't have the LiveHTTPHeaders extension for Firefox installed so you can sniff the URLs as it grabs stuff.  Bwahahaha.

(Actually, I usually just use an extension that lets me search the cache.)

And if I don't use Firefox?
Anyway, the intention of blip.tv seems to be not to allow users downloading content, at least in no obvious way. They're probably just too lazy to implement more strict DRM. Same with Youtube.

Nice talk!  The "Try THAT with iterators, @"($#* !" part was especially entertaining. XD

What I didn't get was why range.front is so much superior to *i.  At the end of the day they're both just functions returning whatever they please.

range.front could insert a cheap check for validity, i.e. assert(!empty). *i has no chance; it puts the burden of precondition on its user.
