- Add support for assignments within expressions, e.g., `x[y++] = z;` or `x = (y *= 2) - 1;`. The logic is handled entirely within the parser by injecting statements into the current procedural block. - Add support for pre-increment/decrement statements, which are behaviorally equivalent to post-increment/decrement statements. - Fix non-standard attribute position used for post-increment/decrement statements.
