From Jakko Jarvi lambda lib
<https://pdfs.semanticscholar.org/06e4/a10a9603fb72decb778f2ca2129da90135ba.pdf>,
we got good things, most of it inspired variadic templates and std::tuple,
but a little bit was left aside...
Is there any proposals to make placeholders great again ?

using namespace std::placeholders;

std::vector<int> c = {1, 89, 24, 3};
auto it = std::find_if( c.begin(), c.end(), _1 > 10); // instead of:
//auto it = std::find_if( c.begin(), c.end(), [](auto& i) { return i > 10;
} );


allowing operators on placeholders to return predicates ? ( and other
interesting things )
