Ubuntu plans to remove python2 from the desktop CD images in 14.04 [2], so having code that does not work with python3 will become more painful pretty soon. Note that RHEL5 has only python2.4 and will be supported through March, 2017. Since it is not feasible to have code that works in both python3 and any versions prior to python2.6, any chosen dialect will be broken by default on some major distributions that still have full vendor support. > A couple of thoughts while we're on the subject: > > 1.

Some distributions have been nice enough to provide python2 symlinks anyway. Michael's rationale that at least the error message is obvious still stands. > Debian uses an alternatives mechanism to have multiple versions of the > same package Alternatives is global configuration that doesn't really solve this problem anyway.
