Nope. But it returns a reference. However, .At invalidates references to Vector.... So if the left side of statement is evaluated before the right side, you have "free block overwrite"...

Uhmmm... what is the reason of invalidating the ref ? At() isn't the same as operator [], for array ? The only reason to invalidate the ref I could imagine is that At() (can) make a deep copy of array...

BTW, I was thinkin' about it yesterday.... why did you use the pick_ stuff instead of something like a pimpl object with copy-on-write ? It's not feasible ?
