Include a `nameof<>()` utility #112

Open bkietz opened 4 years ago

bkietz commented 4 years ago

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.

As a frequent user of the DEMANGLE macro from Rcpp, I would definitely welcome this.
