Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is WebAssembly magic performance pixie dust?
I bench-marked using Intel vTune.
for loop is interesting. It's why Tensorflow Core written in C++ instead Java.
I don't know any complex C++ program that employ their own GCs when C++ has RAII which is superior to GC.
Just give a try for C++11/14/17 and you will see which one is more maintainable and expressive.
Look at Chromium codebase. It's the most beautiful codebase I've ever been to.
I've done a lot of CRUD web apps in C++ using expresscpp [1] and I would say it's easy as ABC.
A lot of Java folks haven't tried C++11/14/17 (Modern C++).
C++ is Zen of OOP.

Building a Cloud Database from Scratch: Why We Moved from C++ to Rust
E.g. see this implementation: https://ricab.github.io/scope_guard/
But also I should make the point that you generally don't need to write defer-like statements at all when using RAII because it's implemented in the actual type. So it's only more code overall for types that are used only once or maybe twice.

Possible compiler error ?
Meanwhile I will check and use https://github.com/ricab/scope_guard

> low level details leak into your high level description of code, making the two coupled. You can’t make them invisible.
It's your job to make it not to leak. You have to write Modern C++ wrappers around C libs.
Similarity, The same can be said for Java. You can do low level in Java.
C++ is not C. C++ has backward compatibility with C.
Look at Boost folks, they wrote a Modern C++ wrapper around a C HTTP parser.
> And as I said, I’m familiar with RAII, it’s really great when the given object is scope-based, but can’t do anything otherwise.
Nothing is impossible.
You can use Scope Exit Guard with QT Widget.
https://github.com/ricab/scope_guard
> And if the new subclass has some non-standard object life cycle you HAVE to handle that case somewhere else, modifying another aspect of the code. It is not invisible, unless you want leaking code/memory corruption.
Again, Scope Exit Guards solve your problem!
