Description

This parses:

world union-my-world-a {
    include world-one;
    include world-two with { a as b }
}

but if I add a ; to the with it fails

world union-my-world-a {
    include world-one;
    include world-two with { a as b };
}

Is that intentional or is there a reason for that?

Research direction

Start by running the two WIT snippets from the issue through the project's parser and compare how the include forms are handled. Trace the relevant WIT grammar or parser entry point; done means the semicolon behavior is made consistent or explicitly clarified, with both examples covered by a regression test.
