Yeah, it allows working with multiple Python versions fine, like not just 2 vs 3 like on modern Linuxes, but also having one virtualnenv use 2.4, another 2.7, another 3.6 etc. Couple this with good support for Windows too, and it's basically the only usable cross platform Python version manager... kind of sad all this functionality is not baked into core CPython's package, it would make language adoption 10x easier since "multiple python madness" is what trips newbies, especially if they use Windows or a Linux they don't administer themselves... Also nicely optimized precompiled stuff, again, for the benefit of new Windows users, for which anything that needs compiling anything has a 50% change of breaking.
