It has always worked since I started Perl (sometime around 5.4).

I'd make an educated guess that it has been available at least as
long as C<(LIST)[@INDICES]> has. That would mean at least ever
since Perl5; likely as early as Perl4.

Why obfuscation? Hash slice as lvalue is extremly elegant and
*very* readable in my opinion. It requires very little verbiage
and communicates the intent clearly.

For me, Perl's extremly expressive data structure access syntax
and its ability to operate on lists without the programmer having
to explicitly iterate is pretty much the main selling point of
the language. I *very* much miss it when I try to work with
machine oriented languages.

    If I had a nickel for every time I've written
    "for (i = 0; i < N; i++)" in C I'd be a millionaire.
