Research direction

Examine the Swift compiler's diagnostic emission for computed property missing type in the type checker or parser. Look for existing fix it implementations for similar missing type diagnostics (e.g., for variables or properties). The fix it should insert a type annotation placeholder like <#Type#> after the property name. The relevant code likely resides in lib/Sema or lib/Parse. Review comments on the issue for any maintainer direction.
