Feature request: autocomplete record members on construction, and variants when pattern matching

[zth]

This is a feature request/idea that I'm sure you're already well aware of, but I'll go ahead and add it here anyway. Two things that I think would greatly enhance the experience of using ReScript day-to-day is:

1. Completing record members when constructing records
2. Completing variants when pattern matching

I've included a "repro"/examples of what I mean here: https://github.com/zth/rescript-editor-tooling-playground/blob/dd7dd23fd58270683e91dd6e57898e6e40e212d4/src/AutoComplete.res

I understand this is probably non-trivial. But, the type of "exploratory" autocompletion it enables is something that I think is one of the absolute best aspects of the editor integration of for example TypeScript.
