Align `Assignment`/`Function` distinction in AST with compiler's implemented semantics: - The ambiguous case `funcOrVar = expression` is now parsed as a `Function` when in a `Type` definition or in the top level of a module. I.e. it is an `Assignment` in contexts where the RHS is evaluated immediately when the binding is evaluated, and a `Function` in contexts where the RHS is evaluated each time the bound name is evaluated. - `Assignment` statements now may only occur in function bodies. Correcting this distinction lays the groundwork for #11302. Other changes: - Fixed incorrect source code locations for negative literals and negated expressions. # Important Notes New APIs: - The parser now exposes a `parse_block` entry point, which allows parsing input lines as if in the body of a function. The previous entry point has been renamed to `parse_module`. |
