Today I wrote some perl5 code for the umpteenth time. Basically:
for( my $i=0; $i< $#ARGV; $i++ )
{
next unless $ARGV[$i] eq "-f";
$i++;
$ARGV[$i] = absolute_filename $ARGV[$i];
}
chdir "foo";
exec "bar", @ARGV;
I'm trying to work out if there's a clever perl6 way to wri

There is, but it's a different kind of pattern matching:
if @*A
In perl 5:
my @a = (1,2,3);
delete $a[1];
print exists $a[1];
This is false, whereas $a[0] and $a[2] do exist. This is creepy. Not
only is it creepy, it raises a whole bunch of questions with
nontrivial answers:
* does [EMAIL PROTECTED] include nonexistent elements?
* does

If by "stop" you mean "die", yes it would stop.
not what I wanted :-(
Is there some way to associate alternate codeblocks f

Is it possible to have an anonymous multi sub?
This would seem to require new syntax for combining two anonymous
definitions.
Of course we want everythin
