Just a few minor things but overall LGTM! Also, thank you so much for adding that new param type just like we've talked in the open issue! Much appreciated ❤️

I didn't even see #47 - happy to get you guys started 😄

[GiedriusS]

LGTM! Let's wait for a few days to see if anyone else wants to review (:

Thanks! My only little pet peeve of this PR is that in the future we might have other calls with parameters that have the same names so we will have collisions. But, time will tell and that will be refactored (before 1.0) to avoid this problem.

I see, thanks for your report! But only on <1.13 versions because in 1.13 support for underscores has been added. I will fix this soon + add extra versions to our CI to catch these in the future.
