StdLib was a behemoth of a library written by Reini Urban. I think I probably got a nod because I responded to a challenge to write a function to calculate combinations. While I give Reini props for attempting to write and make available such a huge library can't say I ever used it or endorsed it. As I recall it was a highly coupled library, making it challenging for casual use. Having said that I know folks who use it extensively, like my friend David Kozina, so maybe I'm just being a snot.
