in thread 99 Problems in Perl6

Good points, thank you. I suppose if I really want to confuse people (again, pretty darned close to Perl 5):

my $compress = do {
    my $previous;
    sub ($x) {
        $x ne $previous ?? $previous = $x !! return;
    };
}

That works just fine, but it might give someone pause :) Of course, I wouldn't write it like that for production.

Cheers,

    I thought I read recently that in Perl 6, this: 

    ... ?? $previous = $x !! ...;

    would be a syntax error. You need parens (I think Pugs lets you get away with this for now but that will get fixed eventually).

      Indeed, you recall correctly; see 587242.
