Hi,

Since C++23, it's now possible to use multi indexing:
https://en.cppreference.com/w/cpp/language/operators#Array_subscript_operator
So it would come naturally to add the overload:

constexpr basic_string_view basic_string::operator[](size_t start,
size_t end) const;

That would allow the syntax to be very close to python:
if (my_string[5,10] == "something") { ... }

Has that been considered?

Best REgards,
Breno G.
