Research direction
Investigate how other LSP autocomplete suggestions are implemented in the Gleam compiler, particularly for constructs like records or custom types. Look at the LSP module (likely in compiler core/src/lsp/) and the AST representation for bit arrays. Determine what completion items (e.g., size, type, signedness) should be offered and how to trigger them. Check the issue comments for any additional context. The goal is to add autocomplete options when typing inside a bit array literal.
