Unable to give completions to LSP for dot completions

[u9g]

The following code can't be completed using ctrl+space because it fails to parse.

import ct/reflection
import ct/item

pub fn get_item_from_give_code(give_code: String) -> item.Item {
  reflection.
}

You will not know about it though, as compilation silently fails, however when I remove the silent failing, we get the following error:

Panic: C:\Users\---\Documents\code\4-20-24\gleam\compiler-core\src\build\package_compiler.rs:123
	called `Result::unwrap()` on an `Err` value: Parse { path: "c:\\Users\\Jason\\Documents\\code\\4-20-24\\examplemod\\src\\ct\\act.gleam", src: "import ct/reflection\r\nimport ct/item\r\n\r\npub fn get_item_from_give_code(give_code: String) -> item.Item {\r\n  reflection.\r\n  todo\r\n}\r\n", error: ParseError { error: UnexpectedToken { expected: ["A positive integer or a field name."], hint: None }, location: SrcSpan { start: 123, end: 128 } } }

This is a big problem because if we always need completely valid code to offer completions, we can never offer dot completions.

I'm not sure what the next steps are here but I am open to ideas. Maybe something like adding a placeholder for XX.\n to the parser that will allow us to finish parsing the line so that we can still get diagnostics?

Another thing to consider is that the user has no idea there is a parse error if we silently dispose of parse errors.
