I am confused as to which part of my post you are replying to.

While we're staying off topic q/:(/, I am not surprised that their is much
room to speed things up at runtime on a RISC system, but as Perl is very
high level, I think a low level approach using other languages is more
appropriate. But hasn't VLIW pretty much superceded RISC, mainly to make
it easier to get these sort of gains?

Okay, I'm done, before I'm one of the kill file casualties that have
certainly been seen in this thread. ;)
