The naive appooch seemed to work, but when I tried to "dogfood" 
it it just started breaking things, at minimum scaning for 
"private" deleted "private" then it started deleting code that 
matched ""; I used enough git to revert but..... going to need a 
meta program that I dont trust ai to write

May also need token finding functions in general, given phoboes 
sreaching being bad and me being lazy

May need to steal pieces form dscanner(isnt that written by 
someone verbose and safety-ified ;__;)

(will push in 15 minuteish)

Im still wondering about detecting code dupication, this is *the 
most* important piece for what I believe will improve ai code 
quality and what Im most annoyed by, but isnt the usual linters 
job
