I was thinking about lazyness and IO and worked out this potenial
gotcha. In essence its quite simmler to the pipe buffering problems
you sometimes can get in perl5.
my IO $news = io("nntp://nntp.perl.org",:rw); # Open a nntp connection
my $banner = =$news # Throw away the banner. So far so goo

In S06's Currying section, there are some strange looking examples:
&textfrom := &substr.assuming(:str($text) :len(Inf));
&textfrom := &substr.assuming:str($text):len(Inf);
&woof ::= &bark:(Dog).assuming :pitch;
Why is it allowed to omit comma between adverbial pairs, and even
omit
Just wondering - would 'reverse =$foo' call '$foo.previous()' ?

That is how I undestood that. Can someone confirm this belief?
I share your belief. It's up to others to confirm it. I just

The declaration ([EMAIL PROTECTED] is rw) can't be outlawed as it is how Perl 5
default sig translates to Perl 6.
IMHO @args as a parameter works

Hi,
are the following assumptions correct?
sub foo ([EMAIL PROTECTED]) { push @args, 42 }
sub bar ([EMAIL PROTECTED] is rw) { push @args, 42 }
foo @some_array; # dies ("Can't modify constant array...")
bar @some_array;
# works, but does not change @some_array, as the

No, it's for anything that supports iteration... `=$foo` ==
`$foo.next()`, if I recall correctly. It's probably not yet
implemented.
