 - Add support for uncurried mode: a mode where everything is considered uncurried, whether with or without the `.`. This can be turned on with `@@uncurried` locally in a file. For project-level configuration in `bsconfig.json`, there's a boolean config `"uncurried"`, which propagates to dependencies, to turn on uncurried mode.
-Since there's no syntax for partial application in this new mode, introduce `@res.partial foo(x)` to express partial application. This is temporary and will later have some surface syntax.
-Make uncurried functions a subtype of curried functions, and allow application for uncurried functions.
-The `make` function of components is generated as an uncurried function.
-Use best effort to determine the config when formatting a file.
