I’m looking at http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1389r0.html#delayreferences-references

And the code example there is almost literally taken from the textbook I’m writing. P1389 continues:

"Without a genuine use-case, references can make seem C++ look rather quirky! Instead, it is recommended that students be exposed to references in a practical fashion, such as when passing parameters to functions.”

I agree, which is why that code example in my book is preceded by

[cid:B94EB96E-86B3-4E10-9D14-45EC320BED3E]

and followed by

[cid:8C957894-0A1F-44A5-96D0-10F53F39692E]


Ok, so now my question to the author of that statement in P1389: please write a sample explanation of references in the context of parameter passing, without first explaining references.
