Description
At some point I ended up with a pattern that looked like this:
case stuff of
-- other patterns...
_ as foo ->
foo
Any _ as foo -> pattern can be (and seems like it should be) rewritten as foo ->. The latter seems like a strictly better way to write it. 😅

Research direction
No file or test is named. Start by searching the formatter for handling of Elm pattern syntax and existing pattern-formatting tests, using the example as the minimal case. Done means _ as foo -> is formatted as foo -> without changing other patterns, with regression coverage.
