And it would. I'm not on one-side or another here, but I do see the
proposal working just fine.
$ref.fetch($key)
works even when $key is a string and $ref is an ARRAY ref.
$ref[$key]
is shorthand for
$ref.[$key]
which is in turn shorthand for
$ref.fetch($key)
and/or
$ref.store($key)
depending on how it's used.
Allowing $ref to be a hash reference doesn't change anything because
HASH's fetch and store methods (no matter how builtin or pre-optimized
they may be) will do the conversion.
You still need C<{}> vs. C<[]> for anonymous types, but I don't think
you NEED them for indexing. Now the question becomes, do you WANT them
for readability?
