Most Perl 6 will look like Perl 5

If you use curlies, you will have to be explicit just as Abigail said.
But as Mark mentioned, for literal keys this Perl 5 syntactic overload
should be changed to use <> instead.


which is coherent with other uses of <> as a quoting mechanism.

              <a b c>   is  'a', 'b', 'c'
              :k<val>    'k' => 'val'    (constructing a Pair)

And there is also the interpolating counterpart indexing

                %hash<<user {$foo+1}>>

which is equivalent to     %hash{ "user {$foo+1}" }

That means Huffman coding is still there, but distinct things were
made different as many others in Perl 6 (for instance,

* eval {} vs eval STR, which are now    try {} vs eval STR
* x for strings and lists, which are now two operators   1 x 3 (=
'111')  1 xx 3 (= 1, 1, 1)

You could, but I am not sure you should ;-) Subclass the hash
container and create an automethod which returns the stored value at
the given key.
