You might look in the sandbox, specifically in boost/algorithms/all.hpp. What you call "exists" is called "any" there - which follows the proposal for TR2.

Oh yes, so it is! With your name on the file I see. I prefer exists to any, but OTOH I can see the symetry with none, so maybe your version is best. When is this likely to emerge from the shadows? Also, I see you have range versions too - does this need the RangeEx stuff to be in Boost too? Do you think your algorithms should have Boost concept checks on their template parameters? Cheers, Rob.
