Hi Matias,

Thanks a lot for working on this!

I am going to let this sit for a bit because I am not convinced that this is the right way to go.

Note that the package supports many more tests, which introduces a lot more symbols than currently covered in this PR, and it will continue to grow as more tests are supported. So I am wondering if there exists a more general solution to address the issue than the current brute force (and more fragile) way to deal with it.

I will sleep on this a bit more and get back to you! 😄
