In fact, my sentiment extends to hardware design, which is why I've been toying (and building real stuff for work) with SKiDL lately, a Python extension that allows for text based schematic capture for printed circuit board design.

Of course, the actual routing of the traces still must be done by hand. However, during schematic capture, instead of drawing the same Zener diode input protection 100 times with a mouse, I just call the code that builds it in a loop.
