I see the Postscript is the twentieth most popular programming language :-)
Methinks that this list needs to take account of whether or not a programming language is used directly or generated from another program.
Yes, I was that nutcase who strapped a 300 baud dumb terminal to an Apple Laserwriter with a view to drawing wireframe teapots by programming the beast in Postscript directly.
I eventually got my teapots by writing programs (in Pascal as it happens - 17th on the list) that wrote out the Postscript program to a text file.
On the output side of programs that write programs is the natural home of Postscript.
