I just want computer-assisted, approximate pattern recognition.
I would like to be able to say, show me in the text I've written what my tics are, what parts of this code I'm writing look similar to other code already written, where it looks like a common error, an old bug, like a frequently-used command I can alias, a habit I might want to break, a cliche to avoid.
I don't want the computer to create more almost-work repetitiion, I want it to help me see the work I've done clearly.
