in thread Thoughts on Perl6 - Love it? Hate it?

Just out of curiosity, I know there's still a lot up in the air (err?), but won't this be a syntax error?

@seen{@data} ^= 1;

You have an @ to designate "seen" as an array (Perl6 terminology, folks!, I know that's not correct for Perl5), but you're using the curlies for a hash. I am assuming that what you meant to do was use a hash slice of elements in @data and set all elements to 1 (true). If so, I believe that would be:

%seen{@data} ^= 1;

For those not familiar with Perl 6 idioms, that would be the equivalent of the following in Perl 5:

@seen{@data} = (1) x @data; # or foreach (@data) { $seen{ $_ } = 1; }

Cheers,
Ovid

    Dammit. Old habits die hard. I'm going to get flooded with those error messages, I'm sure.
