Of course that might not realy make

just don't want to be able to say "when $a == $b" and thats just
invalid since it would be clearer written as an if.

In order not do do some strange magic could you jsut do:

That seems clear and non magical to me.

T then it might overlap (collide) with a real class named T.
In the following case it is not clear wether Dog is defined in the
signature, or a realy seperate class.
sub test (class Dog $x) {
my Dog $y = $x + 5;
}
The same example with ^ becomes much clearer to me.
sub test (^Dog $x) {
my ^Dog $y = $x + 5;
}
The ^ clearly states the meaning while bareword Dog and 'class Dog'
would both cause conflicts in my head.
Just my reasoning about it all.
BTW didn't you contradict your own real world usage of type1^type2 ?
Even if we use ^ as a sigil why would it get confused on that? I
don't think type1 ^type2 could have any realy meaning so it should be
easy for the parser to know the difference.

Eric is confused. I don't know about in Perl 6-to-be, but in Perl 5
those two mean totally
# Return the iterator as a closure wrt the above variables.
return sub
{
my $i = $index++;
return () if $i >= $max_num; # No more elements to return
return map $_->[$i], @arr_list; # Return ith
@bar)
is very easy to code in perl 5. At the risk of sounding reactionary,
this doesn't seem like a Big Win for perl.

How about:

print $x;
Generate a warning, or not?
Or:
foo();

Generate a warning, or not? Which one? Remember, foo() may initialize $x.
