acr-qml-implicit-handler

This ACR (Automatic Code Review) extension detects the use of implicit signal handlers in QML, such as:

onClicked: {
    doSomething(value)
}

Although this pattern is valid in QML, it relies on the parameter names defined in the original signal. If the parameter name changes, the handler may break silently at runtime.

---

✅ Recommended Style

Always use explicit anonymous functions in signal handlers:

onClicked: function(value) {
    doSomething(value)
}

Even when no parameters are used, prefer:

onSomething: function() {
    // ...
}

This makes the code more resilient, clear, and less dependent on signal internals.
