Description
In range/numeric.hpp, in inner_product, I see the following assertion:
BOOST_ASSERT( boost::distance(rng2) >= boost::distance(rng1) );
A good idea in theory. But rng2 and rng1 can be input ranges. Simply computing the distance will consume the input that the algorithms needs.
Drop the assertions.

I'll drop the assertions for the case where the traversal is < bidirectional.
