From the standard:

Given that I am used to how the STL works, at first I'd expect Boost.Algorithm to follow the same interface where it makes sense-- why would none_of_equal use an interface different from std::find? Now, if truly the STL interface is incorrect and Boost.Algorithm needs to use iterator_traits::value, wouldn't it make sense to also change the STL interface in the C++ standard?
Yes, it would make sense. No, we won't do it, because it would break code.
I think what I am trying to ask is: Does anyone know why std::find does not use use iterator_traits::value?
IIUC it was an oversight, and IIRC Stepanov's later work (EOP) does restrict the type of "value".
I could be misremembering, but didn't iterator_traits come after the first release of the STL? -- Marshall Marshall Clow Idio Software <mailto:mclow.lists@gmail.com> A.D. 1517: Martin Luther nails his 95 Theses to the church door and is promptly moderated down to (-1, Flamebait). -- Yu Suzuki
