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:
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
