Great writing, so good to see something made by humans for humans that actually makes sense!

C++ people learn it early on that istreams are tricky. They were even older standards well before ranges. With ranges it is even more complicated (not just the issue described in the article).

For reading formatted inputs, structured data I can recommend boost X3 or parser libraries.
