compiles ok. Can someone please come up with appropriate BLL magic to resolve this situation? It seems to me, I'd somehow have to dereference bll:_1.

No. The signature that std::max_element expects is bool f(float, float); What you're passing is float f(float);

Yes, I didn't lie, the construct, even though wrong, compiles ok. The snippet below gives the correct result, though float max_height(*std::max_element(hfa.data(), hfa.data() + hfa.num_elements(), bll::bind( static_cast(&std::abs), bll::_1) < bll::bind( static_cast(&std::abs), bll::_2))); What I don't like about it is the use of pointers, Does there exist no prettier approach using iterators?
