Boost.Algorithm: clamp: discrepancy in parameter & return types between code and online documentation

[Martin Moene <m.j.moene@…>]

The online documentation of the clamp algorithm of Boost.Algorithm reads [1]:

template<typename V>
V clamp ( V val, V lo, V hi );

template<typename V, typename Pred>
V clamp ( V val, V lo, V hi, Pred p );

whereas the code [2] passes parameters and return value by const reference. Similarly for the sequence variant.

I'm wondering if this is on purpose or that it is a mistake in the documentation?

It's a mistake in the documentation.
