Show HN: C++ Compiler Support Page

Feature names tend not to be very approachable. They often use very precise terminology or refer to papers with names that are targeted for a very in-the-know population.

As an example, one of the features listed is '`constexpr` `std::shared_ptr` and friends'. You seem to have a search that can cope with backticks but this feature doesn't show up if I search for 'constexpr shared_ptr'. That can be solved technically, but the bigger problem is that this feature also changes things for `weak_ptr` - or 'smart pointers' as a concept.

I can't picture a situation where I end up wanting to know the status of that feature's implementation in isolation.

For what it's worth, cppreference isn't any better at this, since it doesn't have any notes on the addition of support for `constexpr`ness of either pointer type. But with enough will I can change that.

You're not going to find some hobbyist coming up with a useful conformance or coverage test suite for free. It's intensive, expensive, and arduous.

Such things are mandatory, however, if you are a C++ vendor targeting ISO 26262 or IEC 61508 or similar -- basically, software that could kill you if it's done wrong. It's a niche with money and motivation.

There are not enough oldtimers alive to do it, and the younger guys refuse to learn it. That drove up the hourly salaries enormously.
