[ShikChen]

Fixes #2.

Thank you very much for your contribution. This looks great!

I haven't reviewed it in detail, as there seem to be some issues:

• The tests on Windows currently fail with:

  [..macro\tests\demo.cpp:66 (main)] ====== multiple arguments
  [..macro\tests\demo.cpp:68 (main)] The number of arguments mismatch, please check unprotected comma
  [..macro\tests\demo.cpp:68 (main)] test_int, (std::vector<int>{2, 3, 4}), test_string = 42 (int&)
  [..macro\tests\demo.cpp:68 (main)] Y�����U��j�h�m� = {2, 3, 4} (std::vector<int>)

• The displayed types seem to have an additional reference attached as compared to before: before:

  [..macro/tests/demo.cpp:34 (main)] test_int = 42 (int)
  [..macro/tests/demo.cpp:35 (main)] test_float = 3.14 (const float)
  [..macro/tests/demo.cpp:36 (main)] test_bool = false (const bool)

  on this branch:

  [..macro/tests/demo.cpp:34 (main)] test_int = 42 (int&)
  [..macro/tests/demo.cpp:35 (main)] test_float = 3.14 (const float&)
  [..macro/tests/demo.cpp:36 (main)] test_bool = false (const bool&)

Thanks, I will try to fix those issues :)

Both issues should be fixed now. Please help review the PR, thanks :)

It might take some weeks until I find the time to properly review this.
