How to capture argument expression as string literal without using macro?

Question

In C, it is quite common to capture argument as string literl via macro as mentioned in this answer:

#define CALL_DO_SOMETHING(VAR) do_something(#VAR, VAR);

But on the other hand, there are many projects with policies against the usage of macro and recommend always using templates instead.

I am wondering if it is possible to express the similar syntax in a modern C++ way or it is yet another corner case where macro has to be used?

Answer 1

Stringification can only be done by MACRO.
