I have a sequence of tribools and I want element with a indeterminate value to inherit from their neighbours. Hmm, so they pass on "tribool knowledge"?

(sorry)

Sort of, yeah. My current idea is actually a sort of proxy output iterator which keeps a counter of "pending" indeterminate tribools and flushes them to the proxied output iterator once their status becomes known. It should also automatically flush in it's destructor. Then I could just use std::copy with a std::back_inserter in order to convert a sequence including indeterminate values into a sequence just containing bools. Useful? BR, Jens
