Cannot include file for macro expansion

Testing code

• https://wandbox.org/permlink/SOdwYcGYX9nThRXx

• types.hpp

  HANDLE_TYPE(int)
  HANDLE_TYPE(double)
  HANDLE_TYPE(std::string)

• main.cpp

  #include <iostream>
  #include <map>
  #include <string>
  
  int main() {
  
      std::map<std::string, std::string> cache;
  #define HANDLE_TYPE(Type) cache[#Type] = #Type;
  #include "types.hpp"
  
      for (auto &pair: cache) {
          std::cout << pair.first << ": " << pair.second << std::endl;
      }
      return 0;
  }

It prints out:

double: double
int: int
std::string: std::string

It does not work under jupyterlab xeus-cling

#include <iostream>
#include <map>
#include <string>

std::map<std::string, std::string> cache;
#define HANDLE_TYPE(Type) cache[#Type] = #Type;
#include "/tmp/types.hpp"

for (auto &pair: cache) {
    std::cout << pair.first << ": " << pair.second << std::endl;
}

Maybe it's more like a cling thing. :sad:
