That is a good question. The C++ stdlib has some truly bizarre APIs. I wonder if they should freeze std and work on std2.

from_chars is the correct API here. When you're parsing decimal numbers you want to do it with streaming semantics.

Hm but there's nothing streaming about it? You need the entire numeric string in memory

I think they meant the other way around: you can have a single string in memory containing multiple numbers, and process that string as a stream.
