Heredoc issue in pugs.

[Yiyi Hu]

#!/usr/bin/env pugs

my $a = q:t /END/
test
END;

$a.perl.say;

Above example works ok in pugs, But the problem is.

From S02


Heredocs are no longer written with , but with an adverb on any
other quote construct:

   print qq:to/END/;
   Give $amount to the man behind curtain number $curtain.
   END

Which is correct?

Instance attributes collision

[Yiyi Hu]

For perl 6,
Array and Scalar are in different namespace.
So,
 class A { has $.a; has @.a };

what will A.new.a return by default?

An Error? or Scalar has a higher priority?

Is S05 correct?

[Yiyi Hu]

Hmm,
There are sevral appears in S05 which use = instead of - in a for loop.
So, Is this a typo?
eg:
for @{$pairs} = $pair {
say Key: $pair[0];
say Val: $pair[1];
}

Thanks,

Is there a way to generate an object without new?

[Yiyi Hu]

What I want to do, is a bit like...

class A {
has $.b;
method show { $.b.say };
};

A( b = 5 ).show;`

Need correction to S06

[Yiyi Hu]

svnbot6 r6401 | iblech++ |   *%slurpy_hashes exist :)
svnbot6 r6401 | iblech++ |   It uses the semantics of
svnbot6 r6401 | iblech++ |  
http://www.nntp.perl.org/group/perl.perl6.language/22860, i.e.
svnbot6 r6401 | iblech++ | sub foo (*%hash) {...}, foo(hash =
{...}); # works
svnbot6 r6401 | iblech++ | sub foo (*%hash) {...}, foo(hash =
{...}, foo = bar);  # dies


in S06
List parameters section
sub duplicate($n, *%flag, [EMAIL PROTECTED]) {...}
duplicate(3, reverse = 1, collate = 0, 2, 3, 5, 7, 11, 14);
duplicate(3, :reverse, :collate(0), 2, 3, 5, 7, 11, 14);  # same

Should the example changed to?
sub duplicate($n, *%flag, [EMAIL PROTECTED]) {...}
duplicate(3, flag = { reverse = 1,  collate = 0 }, 2, 3, 5, 7, 11, 14);
duplicate(3, flag = { :reverse, :collate(0) }, 2, 3, 5, 7, 11, 14);  # same

duplicate(3, flag = { reverse = 1 },  collate = 0, 2, 3, 5, 7, 11,
14); #error
duplicate(3, flag = { :reverse }, :collate(0), 2, 3, 5, 7, 11 );   # error.


Otherwise, I might confuse many newbie just like I do.

Can a scalar be lazy ?

[Yiyi Hu]

my( $s, $t ); $s = value t is $t; $t = xyz; print $s;
in perl 5, it will give a warning, and won't do right thing.
we have to use other way or eval '$s' before print to get a correct answer.

So I wonder, If we can make $scalar lazy also. As array now is lazy by default.

Even if making scalar lazy might cause problem sometimes, Is it
possible to add a property which is like
my $var is lazy; to handle these situation?

What will happen if the attribute's names are the same but declared with different keyword?

[Yiyi Hu]

class T
{
has $.a =1;
my $.a=2;
};
my T $o .= new;
$o.a().say;

What the result will be please?
1 or 2?
Or an error?

Thanks,
