I don't see anything scary in the changelog, but IMHO this is a case of "Never, EVER buy a first year car!" This is a completely new branch dot-zero release, and it just came out Wednesday.

I'd suggest setting up a mule machine and seeing how your base system responds to a make build/installworld using the new GCC. Until you have the system and kernel compiling well, I would say that Perl and mod_perl should be considered of lesser importance. Certainly it would be criminally stupid to swap out your system's supplied gcc for 4.0 in any kind of an environment that you depend on for either your workstation or a production environment. Many of the improvements are in the speed of the optimizer. There are some goodies that I'd be interested in benching, but, like any optimization, YMMV. Nothing here is worth risking a nickel for.

What I do see -- besides the optimizer and threading improvements -- is the inclusion of more standard containers. I think this will add power to future programming, but, of course, it's a matter of having code that _uses_ them. :D
