ok but BrowserUK already mentioned ... lightweight threads for Perl5

I didn't say that we had lightweight threads for Perl5. Or even that they were possible at this point, though they might be, but I do not antisipate seeing them any time soon. But they could (and I believe should), be at the core of Perl6.

As for what a sysadmin might "possibly need" from Perl 6. That's a non-argument. Everything that you can do in Perl 5 can be done from C or assembler, but few of use would prefer to do our daily work there.

And the more transient and informal our scripts are--lots of sysadmin scripts are one-offs--the less likely we are to want to write at those levels. Try writing this in C or assembler:

perl -e"open $fh[$_],'>','split.'.$_ for 0..9"
-nle"print {$fh[substr $_,3,1]} $_" big.log
