This is even more attractive to me when considered together with
normal element access:
$array->[]; # dereference
$array->[$i]; # single element
$array->[@list]; # array slice
$hash->{}; # dereference
$hash->{$n}; # single element
$hash->{@list}; # hash slice
It bugs me slightly that [] and {} look "empty" when in fact they
return everything, but I like the parallelism more than I fear that
visual confusion. That table above is easy to teach and easy to
remember.
Would we allow whitespace between [] and {}? Or would we treat them
like a type of operator and insist that they be without a space?
