Research direction

Start by reviewing the requested nameof() behavior in the issue and the referenced Apache Arrow commit, since no cpp11 file or test is identified here. Define the supported type-name output and verify that the implementation avoids RTTI and runtime demangling, then add coverage demonstrating the r_string example and other intended generic error-message uses.

Written by the indexing model from the issue text.

Description

feature

It's possible to implement a nameof<T>() which provides a string representation of T without requiring RTTI or demangling at runtime.

assert(nameof<r_string>() == "cpp11::r_string");

This might be helpful in a number of cases including providing better error messages from generics.
