Thanks for working on this @iamshreeram.

My preference would be to find something that looks like a real example, not those h, g,... abstract functions. I think to most people (at least surely myself), understanding the point of that example is not that easy, and it's not obvious to imagine a case where you'd want to use that. I think with something that looks like real data, and real transformations will be much easier.

It's not easy (that's why this hasn't been fixed yet), but surely doable.

Thanks!
