Well, it would be wicked to use <*> to hold magic cookies, since that construct is supposed to only contain literal strings. However, Perl 6 already specs a multidimensional syntax in Synopsis 9 to do what you want:

    $hash{ **; 'foo2'}
    $hash{ 'bar'; **; 'foo2' }

Whether this is actually implementable is another question...

I don't see why it wouldn't be. At worst, you would need to do a breadth-first search through the whole datastructure (which, in the general case, is likely to be a graph rather than a tree). Of course, this may be terribly slow, but surely it's implementable. -- print "Just Another Perl Adept\n";	[reply]
