I'm sure every proposal that added some functions to `basic_= string` said the same thing. That kind of thinking is precisely how you get= bloated interfaces.

Those grains of seemingly irr= elevant sand eventually add up to a desert.

That b= eing said, I don't think `basic_string`'s interface is unnecessa= rily bloated. I find that (most of) those functions are essential, but = mainly because there are no equivalent algorithms that can do those jobs an= ywhere nearly as conveniently, clearly, and effectively.

`str.find("foo"sv)` is hundreds of times more digestible t= han `auto look =3D "foo"sv; std::search(str.begin(), str.end(), l= ook.begin(), look.end());` Range TS gives us `std::search(str, "foo&qu= ot;sv)`, which is pretty reasonable.
