Lists and hashes, while very welcome (!), are somewhat cumbersome to
use with out some syntactic sugar along the lines of what has been
discussed. In addition to:

list[1,2,3]

for a list/array containing another list/array, containing another
list/array, we need, e.g.:

list[3,'foo',2:5]

for a list containing a hash or structure, containing an array or
list. Currently you must use

(list[3])['foo']

A better syntax, if it could be arranged, would be:

list[1][2]

or

list[3]['foo']

Even better if these could function correctly on the LHS of an
assignment.

I'm actually surprised the analogy of hashes with structures wasn't
expressed directly, ala:

list[3].foo

... but that of course brings in the new (and in my opinion
unnecessary and in this case, deleterious) conflation of "." with "-
> ".
