Hi. I'm working on some Haskell code that takes some string input and processes it to return a list of integers, the reason for which should become clear when the app. eventually get finished. The list processing functions do what I want when I call "parse_data (contents)" in GHCi, but …
Here is an amazing article. Peter Norvig does not let small detail, that the language was never implemented in it's time, disturb his debugging the code written without implementation, but single handedly implements it with Python parser. Frustration warning, this is frustratingly amazing stuff: [Prescient but Not Perfect: A Look …
The End.
