@reidrac@social.sdf.org @gilesgoat I use TabNine with a moderate success.
It doesn't pretend to be "your smart coding assistant" and literally a glorified autocomplete.
But it is hit-or-miss even with that. Sometimes it completes too much or picks up a wrong pattern. Sometimes I miss something that it got wrong and had to backtrack. Luckily it is only a line-sized chunk of code, not some "write me a screenful of boilerplate".
So it is net-positive, but marginally so.
Perhaps its main value for me is having a live probe in the state of the art free::beer code automation. If the thing starts to pump solid Haskell I'd be worried... or happy, IDK.
