Error: forward reference to inferred return type of function call

[timotheecour]

test.h:

#define tims_my_def2(x) (2*x)

template<typename T> auto _tims_my_def2(const T& x){
  return tims_my_def2(x);
}

main.d:

modmap (C++) "test3.h";
import (C++) _;
void main(){
  //  (compiled with `-cpp-args=-std=c++14`)
  // Error: forward reference to inferred return type of function call '_tims_my_def2(3)'
  auto a=_tims_my_def2(3);
}

workaround: use this (with -cpp-args=-std=c++11)

template <class T>
constexpr auto _tims_my_def2(const T& x) -> decltype(tims_my_def2(x)) {
	return tims_my_def2(x);
}

Fixed!
