Inspired by Elm, I have been thinking/reading about spreadsheet DSLs.
I know, tangential, right?
I found a nice paper: https://www.microsoft.com/en-us/research/wp-content/uploads/2016/07/excel.pdf
A lot of the concerns it raises, reminds me of how Elm feels to me, i.e. -> great!
Anyone else have readable programming language design material to share?
