Please, tell me if one can write nested lambda expressions like

" template struct pairs: bm::fold>Result, bm::push_back<_1,bm::pair > >{}; template struct AllPairs: bm::fold, pairs<_1,Seq2,_2> >{}; "

without using intermediate metafunctions. This ought to work, since the placeholders in AllPairs will be expanded before

Here I've presented the example of "intermediate metafunction" i.e pairs. And I'm speaking about writing just one metafunction using nested construction. Is it possible? Yours respectfully, Dilas
