Which came from me... I probably should have sent it to the list,
but at the time it seemed something was haywire with my mail. An

Yes. Just Like Perl. What harm harm can possibly come to sticking
with Perl4 in a stable branch? And certainly we've seen major
incompatible changes to C++ at the *ABI-level* in the past.

Yes, I know we don't own C++. That was my whole point. It seems
to me that PHK wants to stick with be very careful with what we
introduce to kernel-level programming, and that seems quite
reasonable and prudent, IMO.
I *like* playing with a wide variety of languages when it comes
to user-level applications, but I can see that we need tighter
control when it comes to the kernel.
