I'm afraid I have to agree.
When I saw it used in code after this discussion (I think it must have
been somewhere in pugs t/ or ext/) my reaction was "yuck".
(for what it's worth)

I would expect these to both equal 1,

Is [EMAIL PROTECTED] the correct way to get a hash slice using elements of an
array?
(it's giving me a compilation error with pugs)

Ok, I've just realised I had missed a '->' to '.' in my perl5 to perl6
conversion,
I was trying to do

I have a class that normally takes a list of named arguments.
I also want to be able to handle a single argument.

Here's a demo script:

class Foo {
multi method new (Class $class: Str $date) {
say "ok";
return $class.new(date => $date);

Agreed.

I've already added a bit about method calls, but I'll leave it alone
for you to do arrays/hashes.

ok, that was quick :)
Shall I remove what I'd already added to the bottom of the file?

1.50 -> 7.10
That's quite a version number jump!
I've updated it, and it works now, thanks.

Is that correct? S12 says...
All classes inherit a default new constructor from Object.
It expects all arguments to be named parameters initializing
attributes of the same name.

Isn't it possible to add a Role to the relevant Class, which specifies
that is 'handles' the method name you want as an alias?

hmm, could we write...
sub foo (Class $self is topic: +$foo, +$bar) {
.method;
}
to avoid having to use ./
?

Brent,
Why not post the original query to p6compiler for their take on it?

Where did you get ALT-155 from?
I've just checked the windows Character Map, and ¢ (cent) is ALT-0162
( If it's not in your startmenu, do start -> run -> charmap )
It displays in Eclipse (3.1.1) whether the Text File Encoding is set to
Cp1252 (default) or UTF-8 or ISO-8859-1

I wish to convert these 2 subroutines to perl6:

}
sub bar {
my $self = shift;
$self->{bar} = defined $_[0] ? shift : $DEFAULT;

That puts my mind at ease!

Are you subscribed to perl6-compiler?
Yesterday Patrick Michaud posted "PGE features update (corrections)"
which describes the results you've got:
