It tells me that "icmp ping requires root privileges". But if set the "uid" bit it

You cannot do this in perl6 because perl6 does not yet exist.
Please do not abuse this mailing list with off-topic questions.

The fact that something can be accomplished in Perl doesn't necessarily mean
its the best or most desirable way to do it. I respect the programming
abilities, but
grep { ref($a) eq ref($b) } @b)
is far less intuitive than the proposal. I could perhaps dig into my distant
memory and explain

I never did figure out why "last" {w,sh,c}ouldn't be made to do
that very thing.

Make some modules, release them, and see how much they're used. Then
one can contemplate sucking them into the core based upon the success
of those modul

I've been known to use:
sub opt(*); # imal quoting! :-)
So I could say if opt(a) sans quoting. But that
breaks for the pseudofuncs like m or s.

grep doesn't short-circuit; you can't return or exit or last out
of the thing.
Maybe we could add support for C to C

No it didn't. :-) Those are cascading headers (read the "by" field),
Sun's internal mail system has 3-4 hops and 2 firewalls to go through.

Why? This is an arbitrary decision if you've declared variables to be
barewords.
Anyways, I'm done harping on this issue. I think a single, simple syntax
is good. Yo

It's rather difficult to keep up with them all, or read them all
retroactively when you miss a few days. It's also hard to grep
them (HTML is the root of all evil). Is there an rsync server that
will dole out the pods for us as needed?

So "last" should return true, or what?
You do need a true value for grep() to claim success.

The last operator doesn't return anything does it? It immediately exits the
loop/block in question.

It is clear to us that that is a comment and not a preprocessor directive.
The #include preprocesso
Just to note that RFC 76 (Builtin: reduce) also proposes this
mechanism as a means of short-circuiting C.

The straightforward way to do that is quite simply:
