Vue.js: Naming Ambiguity in Script Setup Templates Gets a Warning

Today's activity centers on one change, but it closes a gap that's been tracked across four separate issues going back a while. Pull request 15305, from developer itsheng, tackles ambiguous template references in script setup components.
Here's the core issue: when you write script setup, Vue exposes your top-level bindings — imports, variables, functions — directly to the template. But Vue also applies name normalization to match template usage against those bindings. The problem is that normalization can cause two different bindings to resolve to…
This PR, referencing issues 9303 and 11437 among others, doesn't touch the resolution logic itself. It deliberately preserves the existing behavior and generated render output. Instead, it adds a compiler diagnostic so developers get an explicit signal when a template reference is ambiguous. The change touches the…
The takeaway for anyone writing script setup components: this is a maintainability and debugging win, not a behavior change. If you've ever had a template reference quietly point to the wrong variable because two bindings normalized to the…
