Indented function parameters

[edemaine]

Input

foo := (
  x
  ...rest
) -> null

Current Output

const foo = x(...rest)(function () {
  return null;
});

Expected Output

function foo(x, ...rest) {
  return null;
}

Workaround

foo := (
  x
  rest...
) -> null

Plan

@STRd6:

We'll want to add a nested version of NonEmptyParameters similar to how we do object and arrays

In particular to handle inputs like:

function f<T>(
  t:
    item: T
  u:
    item: T
)

(which currently works but doesn't really understand the middle indentation level)
