It's possible the author was going for the meaning of pretty, but there still seem to be a strong personification happening with emphasis on it being a beautiful woman, and it's that aspect that unease me.

Again, you can call your language however you choose too, and I'm not going to judge it by its name, but I still personally find this womanization trend in programming language names a bit weird.

I'll probably get used to it, though it does feel like an interesting meta-psycholigical subject as well. Where are the programming languages named John, Richard and David? Why are we calling a language by a person's name? Why are their logo becoming human facial features?
