expect, TCL and DejaGNU. My first consultancy work assignment: "Paul had to go on an extended vacation. Nobody understands his code, but he says it is almost done. Finish it up, please!" Thanks to DejaGnu and expect, I could write an extensive testsuite, get good test coverage, fix the few missing pieces of code, and deliver a bugfree product in less than the allotted time. (Of course, I'm not sure it was bugfree, but nobody found a single bug in the next couple of years.) Then Python, where I understood that a language doesn't have to be as toylike as TCL to be extensible and embeddable.
