A neutral element for the cross operator seems weird if
t to how they are used in other
expressions of the language).
It is all there somewhere in Section "Literals" of Synopsis 02
(http://perlcabal.org/syn/S02.html#Literals). More specifically, look
for the item that starts with "In addition to q and qq, there is now
the base form Q&

Thank you all for the help so far.

I think small examples are a good idea. The problem is to have much
simpler ways to do some things, like
[~] map { $_ % 10 }, 0 ..^ $len

(Yes. That has been published also in use.perl and PerlMonks. But I am

What is supposed to happen if one says:
class Dog {
has $:tail handles 'wag';
meth wag { # something else than $:tail.wag
}
}
Is it a compilation error? Or one of the definitions prevail (with a
warning or something)?

The declaration ([EMAIL PROTECTED] is rw) can't be outlawed as it is how Perl 5
default sig translates to Perl 6.
IMHO @args as a parameter works

But is there any other case where we need an explicit tail call with "goto"?
And about a way to curry a method with its receiver to a sub, is there
a shorthand?
Thanks,
Adriano.

That has been discussed
The former implementation can be shortened:
sub uniq {
my %h;
return grep { ! $h{$_}++ } @_;
}
But realize that none of the proposed solutions (which are based on
hashes for computing the return) is amenable to the extension Ingo
called for with comparator blocks.

quoting Damian's original mail[1]:

^^
Would not that mean the original order of the first ocurrence is
preserved? This is what Ruby Array#uniq does:
[4,1,2,4,2,3,5].uniq => [ 4, 1, 2, 3, 5]

I guess not. This is Perl and OO is not mandatory, or even desirable
all the time.
