Another potential usage is to provide a scripting language interpreter for a GUI application. Something like how you can script Photoshop with VBScript. In MIDLE's case, the scripting language happens to share the same syntax as the language with which the application itself is written in.
MIDLE as it is now lacks support for program control constructs, e.g. IF/ELSE, FOR, etc, which is pretty much mandatory for a proper scripting language. But it is possible to add them. In fact, this potential now really makes me want to add more features to MIDLE.
