(Carbon lead here)

We tried other names, but we found collisions with essentially all of them. =/ We ended up picking a "least bad", and actually talked to a couple of folks familiar with the old usage to see if it was a worse collision than we realized. They weren't delighted but generally shrugged. So here we are. =/

It's definitely not perfect, but I think it's much more searchable than "C" or some other choices. Ultimately, I think its at least not bad enough to matter compared to the actual project.
