Abstraction design and implementation: `repeat`—Vittorio Romeo

Save to:
Instapaper Pocket Readability

This series of two articles covers the train of thought behind the design and implementation of a simple `repeat` abstraction that, given a number `n` and a function object `f`, invokes `f` `n` times. The abstraction can be used to repeat actions both at run-time and compile-time. The articles also cover importance of propagating `noexcept`-correctness (and the pain caused by it!).

abstraction design and implementation: `repeat`

compile-time `repeat` & `noexcept`-correctness

by Vittorio Romeo

From the articles:

In my previous "passing functions to functions" and "zero-overhead C++17 currying & partial application" articles I've praised C++11 (and newer standards) for allowing us to write "more functional" code. [...] If I want to repeat an action n times, I exactly want to write that in my code:

    repeat(10, []
    {
        foo();
    });

Cannot get simpler than that - let's implement it!
