Re: pluralization idea that keeps bugging me

After a recent exchange on PerlMonks about join, I've been thinking

Any other cute ideas?
No matter what you do it will remain too English-centric. It might
work for Catalan, too. But it will remain totally useless for Arabic
or Chinese.
In any case, i don't understand why should this be in the core language at all.

**{x,y} quantifier
(I'm just studying the intricacies of Perl 6, so please correct me if
i say something stupid or if this has already been discussed before.)
I was looking for the Perl 6 equivalent of
aaa =~ /a{1,3}/
and finally found that it's
aaa ~~ /a**{1 .. 3}/
This looked rather weird, so i asked on IRC what is the mnemonic for it:
http://moritz.faui2k3.org/irclog/out.pl?channel=perl6;date=2007-06-29#id_l602
I got the reply that it is similar to exponentiation of variables in math:
a ** 5 == a * a * a * a * a == a
It makes sense after it is explained and i do like the rationalization
of the range as a list-like range, instead of the comma, but the **
syntax is rather ugly to my taste. Seeing that the ** quantifier is
not yet implemented anyway, I thought what could replace it, and the
best i could find was 1 .. 3.
My rationale is this:
* It looks clean.
* It the chapter about Extensible metasyntax (...) in S05 most
paragraphs begin by A leading X means yadda yadda, where X can be:
* whitespace
* alphabetic character (not alphanumeric!)
* ? $ :: @ % { [ + - . ! ~~
... so numbers are not covered.
* As a side effect, * is a shortcut for 0 .. Inf, + is a shortcut
for 1 .. Inf, ? * is a shortcut for 0 .. 1.
* The ? of non-greediness can come before the closing - 1 .. 3 ?
Any comments?

Another important loss if we were to go with 1..3 would be the
ability to have runtime-dependent ranges; e.g.:
/ ($ntimes) x**{$ntimes} /
That's exactly what i meant by something stupid.
Thanks - my bad.
Named captures (was: **{x,y} quantifier)

That's quite alright, because both interpretations of that sentence
were valid :-). I meant:
/ $ntimes := (\d+) x**{$ntimes} /

Funny - how did it make sense to me the first time around? :)
This prompted me to re-read the parts about Subpattern captures and
Aliasing in S05, and i've got to say that it's *extreme* TMTOWTDI. I'm
happy about it, 'cause i've been wishing for named captures for a long
time, but i'm not sure that i understand it in your example
completely.
The examples of := usage in S05 seem to have notation such as this:
$ntimes := (\d+)
Is $ntimes supposed to be a predefined scalar variable (my $ntimes)?
Or a regex variable?
I'm getting confused ...
