Wow you are a total shill. Obviously PSF is acting hostilely as you are insinuating, because they wanted to minimize confusion, or maybe they just wanted to minimize confusion.
I am not a shill. I am a longtime user of CMUCL and its now-more-popular fork, SBCL. The name collision has been an annoyance for years -- I always have to qualify which Python I'm talking about. This hardly minimizes confusion.
