Accessing IndexedViewContainer as a LazyContainer<SOMECLASS>

[Ivan-SB]

What would be the best way to write something like

for (auto&& x : discreture::combinations(_N, 3)) {
myclass = converter(x);
}

or even better

for (auto&& x : mywrapper(_N, 3)) {
myclass = x;
}

where mywrapper could be something like:

class mywrapper {
private:
decltype(..... discreture::lex_combinations...) lc;
public:
size_type size() const { return lc.size();

but I just find hard to write the signature of

converter(x);

thanks
