Speculations on arenas and custom strings in C++

If I were doing this, I would accept one more C++-ism and implement a user-defined string literal, so one could do:

    "Some text"_s8

The underlying mechanism is even polite enough to supply a length without a horrible array template hack. (A somewhat unusual case where the C mechanism is a complete fail, the older C++ mechanism works but is incredibly ugly, and the newer C++ mechanism is actually straightforward and comprehensible.)

Lost me there already.

Absolutely not. The standard library has a zillion things, most pairs of which are independent and even unrelated. No type traits, no pairs and tuples, no std::arrays etc. - all things that are completely independent from memory management and ownership.

Regarding the template make function, there’s a c++ proposal I’ve been working on: https://wg21.link/p2719

This provides the type being allocated to the operator new implementation.

If you want to experiment here’s the implementation: https://github.com/llvm/llvm-project/pull/113510

No small string optimization?
