- Convert list() and map() compiler functions from if/do-while to do-while loops
- Remove redundant empty literal handling by breaking on right bracket/brace
- Add new test files for duplicate comma, duplicate trailing comma, and empty list/map with comma
- Expand newlines test to cover trailing comma and empty list/map cases
- Simplify trailing_comma tests by removing inline syntax error checks
- Update Test.fail() to handle variable arguments without kwargs
Add test cases verifying that invalid trailing comma syntaxes in list literals
(e.g. `[,]`, `[1,,]`, `[1,,2]`) and map literals (e.g. `{,}`, `{1:1,,}`, `{1:1,,2:2}`)
correctly produce compile errors when evaluated via Meta.eval in a Fiber.
Add support for trailing commas in list literals by checking for TOKEN_RIGHT_BRACKET
after parsing the last element in the list() function. When a trailing comma is
followed by the closing bracket, the loop breaks immediately instead of attempting
to parse another element.
Include a test case verifying that lists with trailing commas parse correctly and
elements are accessible by index.
