Feature Request: Automatic Expansion of uninitialized record fields

When a warning for "Fields of ‘SomeRecord’ not initialised: a, b, c, d" fires, I'd like a `CodeAction` that allows it to initialize all of those rows with typed holes.

Flow would look like this:
1. let thing = SomeRecord{}
2. Ctrl+'.' (or other code action trigger)
3. ~~let thing = SomeRecord{}~~ --> let thing = SomeRecord { a = _, b = _, c = _, d = _ }

The reason that this is somewhat of a big deal is that in the presence of long record names with the conventional prefix based row names (someRecordA, someRecordB, ...), the typing for this is nontrivial and also entirely mechanical and so the editor is perfectly capable of doing this for me.
