Aye, I saw that recently in an Infoworld article. One area where this
could be particularly interesting is for folks embedding Python in
larger commercial applications (ArcGIS, Maya, etc) that already build
their own Python from source with the same C/C++ compiler that they
use to build the rest of the application (so arbitrary Python C
extensions aren't supported).
