int x = 10;
while (x --> 0) // x goes to 0

For every type T the unary operator+(T*) is considered to exist which returns the given pointer as is. Here, T is not restricted to object types but includes function types. A lambda object that didn't capture anything has a conversion operator to a function pointer. The unary + triggers this conversion.

Deducing your intentions

Deducing your intentions by Andrzej Krzemieński

In this post we will briefly describe what class template argument deduction is, and why it works differently than what people often expect.

Class template argument deduction (CTAD) in C++17: P0091R2

auto q = std::make_optional(std::optional<int>{});
// q is optional<optional<int>>
std::optional q (std::optional<int>{});
// q is optional<int> !

Stop with the CTAD FUD!

Today, we’re happy to announce that the vcpkg version of Boost.Hana now just points to the official master repo, instead of our fork.

VS2017 15.9: Step Back – Going Back in C++ Time

Post

In the most recent, 15.9, update to Visual Studio 2017 Enterprise Edition, we’ve added “Step Back” for C++ developers targeting Windows 10 Anniversary Update (1607) and later. With this feature, you can now return to a previous state while debugging without having to restart the entire process.
