I constantly use both lambdas and structured bindings; without this feature, I am having to constantly redeclare every single not-a-variable I use in every lambda level and then maintain these lists every time I add (or remove, due to warnings I get) a usage. Here is one of my lambdas:

nest_.Hatch([&, &commit = commit, &issued = issued, &nonce = nonce, &v = v, &r = r, &s = s, &amount = amount, &ratio = ratio, &start = start, &range = range, &funder = funder, &recipient = recipient, &reveal = reveal, &winner = winner]() noexcept { return [=]() noexcept -> task<void> { try {

And like, at least there I am able to redeclare them in a "natural" way... I also tend to hide lambdas inside of macros to let me build new scope constructs, and if a structured binding happens to float across one of those boundaries I am just screwed and have to declare adapter references in the enclosing scope (which is the same number of name repetitions, but I can't reuse the original name and it uses more boilerplate).
