I did.

After learning the key bindings, I actually found a library book on a pre-CLisp dialect of lisp by some finnish authors and wrote a tool i later used to write my thesis in electrical engineering.

The tool was parsing my matlab files and generated latex, which i then made into the final pdf, complete with formulaes and calculations.

So instead of writing a decent thesis, i learned about makefiles, latex, emacs lisp and the fact that parsers are very interesting.

Also, Lisp felt sooooooo out of this world after pascal, C, Cpp.

Surely, i did not work a single day as an electric engineer.

PS I keep looking for this book to this very day
