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

Are default values supported for attributive parameters in an argument list?
I wish to convert these 2 subroutines to perl6:
sub foo {
my $self = shift;
$self->{foo} = defined $_[0] ? shift : undef;
}
sub bar {
my $self = shift;
$self->{bar} = defined $_[0] ? shift : $DEFAULT;
}
Is th
signatures and have to 'go back' to the
perl5-ish
sub do_this (*%args) { }

That puts my mind at ease!
Many thanks,

Are you subscribed to perl6-compiler?
Yesterday Patrick Michaud posted "PGE features update (corrections)"
which describes the results you've got:
* Match objects for nested captures are nested into the surrounding
capture object. Thus, given
rulesub = p6rule(":w (let) ( (\w+) \:= (\S+) )"

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)

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
[EMAIL PROTECTED] = $obj->list;
I wasn't
I have a class that normally takes a list of named arguments.
I also want to be able to handle a single argument.
class Foo {
multi method new (Class $class: Str $date) {
return $class.bless(date => $date);
}
submethod BUILD ($.date, $.time, $.offset) {

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 ./
?
