I hear and obey, O Mighty Sponsor!
Though I suspect I'll hold off until Larry makes A3 public. Then I'll
release a module that rearranges *all* the operators to their new Perl
6 bindings:
use Operators::Perl6ish;
package MyClass;
sub new { bless [$_[1], 1..10], $_[0] }
sub next { my ($self) = @_; return "next is: " ~ shift(@$self) ~ "\n" }
package main;
my ($str1, $str2) = ('a','z');
my $obj = MyClass.new($str1 ~ $str2);
print $obj.next() for 1..10;
print $obj.[0] ~ "\n";
my $next = 'next';
print $obj.$next;
#etc.

That's BORING. Obviously the right way to do it is to allow lvalue
overloaded operators, and overload "." for everything.

I *guarantee* it!
It will definitely be possible in Perl 6, because even with our primitive
earth technology we can do the reverse today:
###
# in line DotsForArrows.pm:
package DotsForArrows;
use Filter::Simple;
FILTER { s/\b\.(?=[a-z_\$({[])/->/gi };
###
# then in your code:
use DotsForArrows;
package MyClass;
sub new { bless [$_[1], 1..10], $_[0] }
sub next { my ($self) = @_; return "next is: " . shift(@$self) . "\n" }
package main;
my ($str1, $str2) = ("a", "z");
my $obj = MyClass.new($str1 . $str2);
print $obj.next() for 1..10;
print $obj.[0] . "\n";
my $next = 'next';
print $obj.$next;
#etc.
I suppose you'll want me to put that on the CPAN now. ;-)

Apocalypse Two
http://www.perl.com/pub/2001/05/03/wall.html Some quite exciting stuff in there. Array dereferencing will be @foo[23] rather than $foo[23]. Everything will be an object (or at least work like one). No more typeglobs. User-definable quoting operators. And much, much more! .robin. -- "I dreamt the other night that my nose had fallen off" --john melesky
