17 I think you are getting it the other way around.
19 It's not 'we do not need to support C++ properly because there are no
20 C++ packages crucial to Gentoo'. It's rather 'we have no crucial C++
21 packages because C++ support in Gentoo is broken by design'. It is
22 a limitation, not a reason to keep stuff buggy.
24 Think of paludis as a good example. People who'd like to use Paludis
25 will end up with broken package manager from time to time. How are they
26 supposed to rebuild it without a working package manager?
