Don't knock it until you try it! I never was told that I couldn't bring the Brommie in class. I've done so many times, since my first class used to be one of those and I didn't have time to drop the bike off at the lab before class. It really isn't a big deal at all, unless your classroom is the size of a broom closet (which I hope it isn't). After the class, I'd just drop it off at the lab where it would stay under the desk in my office until the next time it was needed. For the library...yeah, I can see the difficulties in that, but if you make friends with the library staff maybe they can show you a place to stash it indoors.
