I have trouble finding things that require more than 10kloc of Tcl but Tcl has been extended since Osterhout sorta faded on it. It has features like namespaces and package management since at least 8.x . Language comparison is always challenging. I've had less trouble with Tcl than with just about any other language. But it rather requires thinking about the problem in certain ways. The main thing it requires is adherence to an event driven model.
