Liberty is the right to do what I like; license, the right to do what you like.
Licensing, or not
You’re kidding, right? Too right. Who puts a license on code they publish on a platform like the internet?
Not I, Moriarty, not I. As a bit of a GNU/Linux advocate, I think publishing code is like opening a birdcage; when they’re out they’re gone and you lose all control. Unless your bird is a gyrfalcon, trained on the lure. Or a homing pigeon. Okay, that didn’t work. Here’s another: It’s like opening the gate to a field full of wild horses. There, that’s got it.
Slapping a license with restrictions of any kind on a library like TheGHOUL seems to me to be an exercise in futility. Who’s going to enforce Attribution, Share Alike, or even a GPL? I have better things to do, my friend, and if you’re not going to enforce it (and nobody does), why the license? Please don’t say silly things like 'honesty', and 'in good faith'…
So, since I’m fairly confident someone will copy my code and not even remember my name, I’ve saved myself the worry:
The GHOUL, the whole kit 'n caboodle, lives under the burden of 
The Unlicense.
Just let go.
