Re: [PATCH v13 0/3] MR10897: vbscript: Handle declaration scope in the parser.

[Jacek Caban (＠jacek)]

Could we just have something like:
```
    | SourceElements SimpleStatement StSep  { source_add_statement(ctx, $2); }
    | SourceElements ClassDeclaration StSep { source_add_class(ctx, $2); }
```
instead of GlobalUnit?

Calling `source_add_statement` on GlobalUnit result makes it look like it's a statement, while it's really not.
