There's always the Perl 5 hack:
\do { my $x }
Although that's not truly anonymous, I suppose.

which discusses character class syntax in Perl 6, I have some comments to

First, I've been very interested in seeing proper set notation for char
classes in Perl 5. I was pretty vocal about it during TPC in 2002, I

Can't the [] and {} syntaxes be considered aliases for new Array(...)
and new Hash(...)?
my $x := new int = 10; # looks like it should work

Hi,
what is the default invocant of methods?
method blarb ($normal_param) {...}
# Same as
method blarb (Class | ::?CLASS $invocant: $normal_param) {...}
# or
method blarb (::?CLASS $invocant: $normal_param) {...}
# ?
I prefer the latter, as then one can't accidentally call a instance
When we heard that Larry didn't acutally want $$foo to infinitely
dereference, some of us were overjoyed, and others severely
disappointed. Both transparent dereferencing (infinite $$foo) and
opaque dereferencing (one-level $$foo) have their uses, but they are
definitely distinct. Instead of addi

Good idea. A mode

I don't know, but guess not.
Do (most of) the basic types morph themselves into Codes, when needed?
I don't consider it type morphing. If your examples parse
at all they will be dispatched as usual

HaloO Juerd,

Then we lose the point for having different sigils, and everything gets
a dollar sign.
Isn't the strong type system adequate compensation?
Especially when the sigils denote the level below
which you can't go in untypedness
