All~
I have been struggling with my internet for the past 4 days, so this
weeks summary will be part of a "double feature" fortnight's summary
next week. Figured that I would provide advanced notice though...

Actually, I think that p6l is the correct place for this discussion.
My logic is that you are asking about specific facets of the language,
not helping the perl 6 compiler or parrot.

What if junctions collapsed into junctions of the valid options under
some circumstances, so
my $x = any(1,2,3,4,5,6,7);
if(is_prime($x) # $x = any(2,3,5,7)
and is_even($x) # $x = any(2)
and $x > 2) # $x = any()

I believe bool::true and bool::false are enums (so they are 1 and 0,
respectively).

Perl 6 Summary for 2005-02-08 through 2005-02-22

Welcome to yet another fortnight summary. Lately p6l has been out

And this:

believe that some of these can already be handled by C<.as()>.
I would like for this to be addressed. This is one item that has
always confused me about Perl 5.

Too bad sub names can't start with numbers:
0x $hex; # hex $hex
0x($hex);
0b $bin;
0o $oct;
That would make sense to me.

e don't need `splice` and
`substr` at all, but there are times when it's more convenient to
specify with a starting point and a length than with a range.

Chip, in a circumloquacious attempt to come up to speed, indirectly
asked what design issues needed attention. Leo explained the CPS issues

And if I understand correctly, that means that I want everything to
use chars by default. And C<$string[]> would be a nice shortcut for
that.

ntly saw some of this on Linux as well. I didn't go as far
as to define --icudatadir, but I noticed that passing no icu options
causes Configure.pl to autodetect icu. You might give that a shot.
Please consider patching the documentation if what you find there doesn't work.

That brings me to another idea. Is $_ as an array used? @_?
This relates back to the discussion on topic
simply using the autothreading semantics
of junctions. The isa() call will be made repeatedly with the
different arguments and then the junction will know how to combine
that into a single boolean result.

I am confused as to why exactly this is the case. Are you saying that
nested lists like this flatten? That would certainly catch me off
guard
go with it.
Does this mean private methods will be called like this?
./:method()
FWIW, I like the original spec best. I'm not sure that the problems
with it aren't being exaggerated. But I've not written much Perl 6 yet
either...

What does the reduce metaoperator do with an empty list?
my @a;
[+] @a; # 0? exception?
[*] @a; # 1? exception?
[<] @a; # false?
[||] @a; # false?
[&&] @a; # true?
Also if it magically supplies some correct like the above, how does it
know what that value is?
Thanks,

On the contrary a mathematician would say that the empty list is
