Well, no, it can't really. $a[0] now means what Perl 5 called $a->[0]
(or @$a[0]). So it's still an array subscript, it's just subscripting
$a, not @a.
But there's talk about using the various character type methods to
return lists of characters. So if you want the first byte of your
string, you can say:
$str.bytes[0];
And if you want the first codepoint:
$str.codepoints[0];
Etc.
