Alternative API for creating ParamSet objects, using nonstandard evaluation to enable short and concise input.

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.

berndbischl commented 6 years ago

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?

mb706 commented 6 years ago

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.
