Not 'engineering' programming, but real engineering programming. I did a lot of that. Automotive, aerospace, space shuttle, power stations and such.

No syntax or type bugs, just logical or more like physical bugs. Because you are modelling physics, and sometimes the model is just not good enough. Still vastly better than traditional C++ models.

Problems: No diff tool. You can hardly see what changed. That is like shipping updated lisp images or binaries without source code to the devs. You also get a lot of windows, like 30 for a typical small model.
