В stringzilla тоже есть конкатенация строковыми выражениями, но не
так удобна и развита, как в simstr.
Stringzilla also has concatenation by expression templates,
but it's not as convenient or advanced as simstr.

If the concatenation result is less than 207 characters,
it is collected in a stack-based buffer, without allocation or deallocation.

Обратите внимание, что WASM - 32-битный, и там размер
SSO у std::string меньше, насколько я помню, 11 символов + 0.
SSO у std::string меньше, 10 символов + 0.
The jump where SSO ends and allocation begins is clearly visible.
Note that WASM is 32-bit, and the size of the SSO for std::string is
smaller, as far as I remember: 11 characters + 0.

- Parsing double for `char` and `wchar_t`, as well as character types compatible with them in size.

- Разбиение (split) строк на части по заданному разделителю. Разбиение возможно сразу в контейнер со строками, либо вызовом функтора для
каждой подстроки, либо путем итерации с помощью итератора `Splitter`.
- Создании копии со сменой регистра ASCII символов.
- Функции модификации стандартных строк строковыми выражениями:
- str::append, str::prepend, str::insert, str::change - меняют str::string строковыми выражениями,
например `str::append(text, "count = "_ss + count)`.
- str::replace - заменяет вхождения искомой подстроки на строку замены или строковое выражение.
Если подстрока не найдена, строковое выражение даже не вычисляется.
- Парсинг целых чисел с возможностью "тонкой" настройки при компиляции - можно задавать опции проверки переполнения,
пропуск пробельных символов, конкретное основание счисления либо автовыбор по префиксам `0x`, `0`, `0b`, `0o`,
допустимость знака `+`. Парсинг реализован для всех видов строк и символов.
