Pretty much all the magic happens in R/ParamSetSugar.R.

It looks nice. What are your thoughts on putting it in a little extra package. ParamHelperHelper? :sweat_smile: Just in case we can not decide whether we want a new meta language to be part of PH.

it really shouldnt go into yet another package. but we might put it into PH2? that seems pretty advanced and we can then push a bigger change through?

What is the ETA of that? Does PH2 break much compatibility with the current "ParamHelpers"? I rely on Param Set Sugar in mlrCPO, but medium term I can also just ship it in mlrCPO if you think it doesn't belong here.
