As you requested: https://ghostbin.com/paste/zba9f https://ghostbin.com/paste/zba9f This is the simplified version making the same output of the lisp version. I was wondering about race conditions when I try close the read stream on finally keyword. Seems crash sometimes. However I never got this on the Lisp version. Funny. I hope you like it. Maybe I should push this version to the repository?
