I haven't used AutoCAD since R13 and I was still a teenager working in an engineering office, but it was one of the best GUI/CLI hybrids I've ever used. You could learn with the GUI, and it would parrot the CLI commands in the command window. Eventually, you'd familiarize with the CLI commands through pointyclicky GUI usage and just rip through work at ridiculous speeds. Mapping the commands (lisp-based DSL if I remember correctly...) to left-hand-only single key macros while your right hand moused the coordinates on the canvas ... holy crap was that fast. You could whip up fully qualified engineering drawings in a matter of minutes.
