range-based iteration over linq expression without to_vector()

[PhilippC]

maybe this is possible already, but I haven't found out how.

If I have a

auto my_elements = linq::from().where(...).select(..);

how can I iterate over those?

Currently I am doing

for (auto el: my_elements.to_vector())

but that seems inefficient. Is there a way to return an iterator pair from my_elements?

Use the for_each function on interactive:

linq::from(people)
    .select([](Person& person){ return person.name; })
    .for_each([](std::string& name){ std::cout << name << std::endl; });
