 The [Basler AG](https://www.baslerweb.com) company provides a [TCL](https://docs.baslerweb.com/visualapplets/files/documents/TCL/Content/4_VisualApplets/TCL/Intro.htm) scripting engine to automatize the creation of [VisualApplets](https://www.baslerweb.com/en/products/frame-grabber-portfolio/visualapplets) designs (a former Silicon Software GmbH technology), which is a nice and useful feature but not nice enough, in my opinion.

 Huh, to script a script? Too much meta? Let's study an example...

 Just for practical reasons, we encapsulate the operator logic in a `HierarchicalBox`. So it can be reused many times in a VisualApplets design. Consequently we also create a class in our Python script, for the same purpose of course.

 Obviously there are more possibilities to implement the ReLU function. You can replace the fallback value by the `XOR` result or also only check the sign bit of the input value. But the preferred way is probably to utilize the built-in `ClipLow` operator instead... ;-)
