Thank you, this looks exactly like what I'm looking for. Now I'll just have to try it on larger examples to see how approximate it is 😊

Hi Gergo,

Source Notes are what you are looking for. Currently the only way to enable them is to either use `-g` or `-finfo-table-map`. The result will be core which contains nodes which attempt to describe where the core expression came from, it's not perfect though!

See Section 5.4 - https://clicktime.symantec.com/3QgzZCkQPV23ts2BtD4WH4Z7VN?u=https%3A%2F%2Fetheses.whiterose.ac.uk%2F8321%2F1%2Fthesis.pdf
