; Explain to Ayal:
; 1. interleaved log
; 1.1. (try)
; 2. FP IS SO GOOD WHAT
; 3. never use #() unless its SUPER SHORT REALLY
; 4. Hardly use closures its too hard to follow them use thigns like for
; 5. WE MUST HAVE A "Lisp Editor" (which will also be a JSON editor in effect, etc). THESE PARENTHESIS MATCHING AND
;    NEWLINE CALCULATINON ARE TOO HARD
