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,

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
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)?

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

I just posted a report on this first week of the series of
micro-articles on Perl 6 operators. Read it at use.perl:

Thank you all for the help so far.

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

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]
The b
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.
